How to See the 2023 Quadrantids Meteor Shower Peak Tonight in a Flurry of Fire

By Wednesday, your last best chance to see any shooting stars or fireballs for a while will be over, so plan accordingly. 

The first few months of the year have a relative dearth of meteor showers, so it’s worth trying to catch the Quadrantids during their very short peak just after New Year’s.

While December is packed with opportunities to catch abundant Geminid and Ursid meteors, the Quadrantid meteor shower is the sole major shower in the first quarter of the year, and it peaks quite briefly Tuesday night and Wednesday morning this week. 

Like the Geminids and Ursids, the Quadrantids are often among the strongest showers of the year, but these meteors don’t get nearly as much hype as the northern summertime Perseids in August that hit during summer vacation time for many skywatchers. Also, the window of opportunity to see Quadrantids is very narrow, with a peak of intense activity that is just six hours long this year, according to the American Meteor Society. 

Other showers may have peaks that last a day or two, with a lesser but still decent amount of activity stretching for days before and after the actual peak. 

If you’re hoping to catch the Quadrantids this year, there’s two factors to consider: what time the shower will be peaking in your location and how high the quadrant of the night sky where Quadrantid meteors appear to originate from will be at that time. 

Predicting the exact moment of peak activity for a meteor shower offers no guarantees, but the target range for best viewing times is between 3:40 a.m. and 6:40 a.m. UTC on Jan. 4 (7:40 p.m. to 10:40 p.m. PT on Tuesday). That said, the area of the sky that Quadrantids radiate outward from is in the area of the constellation of Bootes the herdsman, and this radiant is highest in the sky between about 2 a.m. and 6 a.m. local time. 

Find where these two windows overlap in the Northern Hemisphere (the radiant will be mostly below the horizon south of the equator, unfortunately) and you’ve got the best spots on the planet for observing the Quadrantids. This looks to be just about any locale in or near the North Atlantic. But again, peak predictions aren’t exact, so it’s worth venturing out to see what you can spot from just about anywhere with clear skies in Europe or North America on Tuesday night or Wednesday morning.

Head outside with plenty of refreshments and warm clothes and give yourself at least an hour for the whole viewing experience. You’ll need about 15 minutes for your eyes to fully adjust and plenty of time to spot shooting stars, which inevitably seem to come in short bursts after long lulls in activity. 

Lie on your back with a wide view of the clear sky and orient yourself to the northeast to face the right radiant. You can expect to see about 25 Quadrantids per hour under ideal conditions, including plenty of fleeting shooting stars and a few fireballs, if you’re lucky. You could get lucky with an outburst of Quadrantids that produces up to 120 meteors per hour, according to some predictions. 

One potential challenge is that the moon will be about 92% full Wednesday morning, so you may need to adjust your viewing plan to put the bright moon at your back. 

What you’re actually seeing when a Quadrantid meteor streaks across the sky is a mote or pebble-size piece of the Asteroid 2003 EH1, which some astronomers believe may be an extinct comet or a new type of object sometimes called a “rock comet.” Over the centuries, EH1 has left a trail of debris in its path and our planet passes through that stream of detritus each January. 

If the weather cooperates where you are, consider making the effort to get outside and look up early Wednesday, because the next major meteor shower isn’t until April.

Quadrantid meteor shower: January’s first celestial event

CNN
 — 

The new year kicks off with the Quadrantids, one of 12 annual meteor showers.

The celestial event is typically among the strongest meteor showers and is expected to peak overnight January 3 and 4, according to the American Meteor Society. Sky-gazers in the Northern Hemisphere can best view the shower between the late-night hours of Tuesday and dawn on Wednesday.

However, the shower is notoriously hard to observe due to its brief peak of six hours and January’s often inclement weather in the Northern Hemisphere. A bright, nearly full moon will make the Quadrantids even less visible this year.

Moonset will occur just before dawn, providing a very small window to spot the shower against dark skies.

Predictions for the shower’s peak range from 10:40 p.m. to 1:40 a.m. ET (3:40 a.m. to 6:40 a.m. Greenwich Mean Time). The later time favors those in the eastern part of North America and the earlier time is more favorable for observers across Europe. The Quadrantids won’t be visible in the Southern Hemisphere because the shower’s radiant point doesn’t rise that high in its sky before dawn.

Check Time and Date’s site to see what your chances are like to view the event, or step outside to take a look for yourself. The Virtual Telescope Project will also have a live stream of the shower over Rome.

Between 50 and 100 meteors are typically visible per hour, especially in rural areas, although the peak can include up to 120 visible meteors in an hour.

Watch the northeastern sky, and look about halfway up. You may even glimpse some fireballs during the meteor shower. View the skies for at least an hour, the American Meteor Society advises.

If you live in an urban area, you may want to drive to a place that isn’t full of bright city lights. If you’re able to find an area unaffected by light pollution, meteors could be visible every couple of minutes from late evening until dawn.

Find an open area with a wide view of the sky. Make sure you have a chair or blanket so you can look straight up. And give your eyes about 20 to 30 minutes to adjust to the darkness — without looking at your phone — so the meteors will be easier to spot.

If the meteor shower’s name sounds odd, it’s probably because it doesn’t sound like it’s related to a constellation, like other meteor showers. That’s because the Quadrantids’ namesake constellation no longer exists — at least, not as a recognized constellation.

The constellation Quadrans Muralis, first observed and noted in 1795 between Boötes and Draco, is no longer included in the International Astronomical Union’s list of modern constellations because it’s considered obsolete and isn’t used as a landmark for celestial navigation anymore, according to EarthSky.

Like the Geminid meteor shower, the Quadrantid comes from a mysterious asteroid or “rock comet,” rather than an icy comet, which is unusual. This particular asteroid is 2003 EH1, which takes 5.52 years to complete one orbit around the sun. The shower’s peak is short because only a small stream of particles interacts with our atmosphere, and the stream occurs at a perpendicular angle. Each year, Earth passes through this debris trail for a short time.

In addition to the meteor shower, a recently discovered comet will soon make its appearance in January’s night sky.

Discovered in March 2022, the comet will make its closest approach to the sun on January 12, according to NASA. The comet, spotted by astronomers using the Zwicky Transient Facility at the Palomar Observatory in San Diego County, California, is named C/2022 E3 (ZTF) and will make its closest pass of Earth on February 2.

The comet should be visible through binoculars in the morning sky for sky-watchers in the Northern Hemisphere during most of January and those in the Southern Hemisphere in early February, according to NASA.

Here are the rest of 2023’s top sky events, so you can have your binoculars and telescope ready.

Mark your calendar with the peak dates of other showers to watch in 2023:

  • Lyrids: April 22-23
  • Eta Aquariids: May 5-6
  • Southern delta Aquariids: July 30-31
  • Alpha Capricornids: July 30-31
  • Perseids: August 12-13
  • Orionids: October 20-21
  • Southern Taurids: November 4-5
  • Northern Taurids: November 11-12
  • Leonids: November 17-18
  • Geminids: December 13-14
  • Ursids: December 21-22

Most years, there are 12 full moons — one for each month. But in 2023, there will be 13 full moons, with two occurring in August.

The second full moon in one month is known as a blue moon, like the phrase “once in a blue moon,” according to NASA. Typically, full moons occur every 29 days, while most months in our calendar last 30 or 31 days, so the months and moon phases don’t always align. This results in a blue moon about every 2.5 years.

The two full moons in August can also be considered supermoons, according to EarthSky. Definitions of a supermoon vary, but the term generally denotes a full moon that is brighter and closer to Earth than normal and thus appears larger in the night sky.

Some astronomers say the phenomenon occurs when the moon is within 90% of perigee — its closest approach to Earth in orbit. By that definition, the full moon for July will also be considered a supermoon event, according to EarthSky.

Here is the list of full moons for 2023, according to the Farmer’s Almanac:

  • January 6: Wolf moon
  • February 5: Snow moon
  • March 7: Worm moon
  • April 6: Pink moon
  • May 5: Flower moon
  • June 3: Strawberry moon
  • July 3: Buck moon
  • August 1: Sturgeon moon
  • August 30: Blue moon
  • September 29: Harvest moon
  • October 28: Hunter’s moon
  • November 27: Beaver moon
  • December 26: Cold moon

While these are the popularized names associated with the monthly full moon, each one carries its own significance across Native American tribes (with many also referred to by differing names).

There will be two solar eclipses and two lunar eclipses in 2023.

A total solar eclipse will occur on April 20, visible to those in Australia, New Zealand, Southeast Asia and Antarctica. This kind of event occurs when the moon moves between the sun and Earth, blocking out the sun.

And for some sky-watchers in Indonesia, parts of Australia and Papua New Guinea, it will actually be a hybrid solar eclipse. The curvature of Earth’s surface can cause some eclipses to shift between total and annular as the moon’s shadow moves across the globe, according to NASA.

Like a total solar eclipse, the moon passes between the sun and the Earth during an annular eclipse — but it occurs when the moon is at or near its farthest point from Earth, according to NASA. This causes the moon to appear smaller than the sun, so it doesn’t completely block out our star and creates a glowing ring around the moon.

A Western Hemisphere-sweeping annular solar eclipse will occur on October 14 and be visible across the Americas.

Be sure to wear proper eclipse glasses to safely view solar eclipses, as the sun’s light can be damaging to the eye.

Meanwhile, a lunar eclipse can occur only during a full moon when the sun, Earth and moon align and the moon passes into Earth’s shadow. When this occurs, Earth casts two shadows on the moon during the eclipse. The partial outer shadow is called the penumbra; the full, dark shadow is the umbra.

When the full moon moves into Earth’s shadow, it darkens, but it won’t disappear. Instead, sunlight passing through Earth’s atmosphere lights the moon in a dramatic fashion, turning it red — which is why the event is often referred to as a “blood moon.”

Depending on the weather conditions in your area, it may be a rusty or brick-colored red. This happens because blue light undergoes stronger atmospheric scattering, so red light will be the most dominant color highlighted as sunlight passes through the atmosphere and casts it on the moon.

A penumbral lunar eclipse will occur on May 5 for those in Africa, Asia and Australia. This less dramatic version of a lunar eclipse happens when the moon moves through the penumbra, or the faint, outer part of Earth’s shadow.

A partial lunar eclipse of the hunter’s moon on October 28 will be visible to those in Europe, Asia, Australia, Africa, parts of North America and much of South America. Partial eclipses occur when the sun, Earth and moon don’t completely align, so only part of the moon passes into shadow.

Intel Meteor Lake-S Desktop CPUs Rumored To Be Cancelled, LGA 1851 Might Support Trio of Core Families

New rumors regarding the Intel Core Desktop CPU family have been stirred up by OneRaichu who states that Meteor Lake may not come to the LGA 1851 socket.

Intel Cans Meteor Lake CPUs For Desktop, LGA 1851 Socket To Support Three Core Families, Alleges Rumor

There were rumors that Intel might cancel Meteor Lake CPUs for desktop release and it looks like those might be coming true. According to OneRaichu who has been very accurate with his leaks in the past, the leaker states that the Meteor Lake-S Desktop CPUs may not be launching on desktop platforms but will still be headed to the mobility segment. A few months ago, we reported original Meteor Lake-S plans which include various SKUs for the desktop LGA 1851 platform. The SKUs list includes:

  • Meteor Lake-S 22 (6P + 16E) / 4 Xe Cores / 125W TDP
  • Meteor Lake-S 22 (6P + 16E) / 4 Xe Cores / 65W TDP
  • Meteor Lake-S 22 (6P + 16E) / 4 Xe Cores / 35W TDP
  • Meteor Lake-S 14 (6P + 8E) / 4 Xe Cores / 65WTDP
  • Meteor Lake-S 14 (6P + 8E) / 4 Xe Cores / 35WTDP

But with Intel Meteor Lake-S allegedly canceled, it looks like we have to revise what we know about the Intel Desktop Core lineup. So starting with 2023, Intel plans to launch the Raptor Lake Refresh CPU family which will replace the existing chips with higher core clocks and an optimized process to enable better power delivery. The latest roadmap confirms this and they will be compatible with all existing LGA 1700/1800 socketed motherboards. This would mean that the current socket would last a good three generations of CPUs.

But LGA 1700/1800 won’t be the only socket that lasts three generations. Rumors suggest that the next-generation LGA 1851 socket might also support at least three generations of CPUs. Since MTL (Meteor Lake-S) is out of the equation now as far as rumors are concerned, the three families we can expect to see on the next socket would have to be Arrow Lake-S (ARL-S), a possible Arrow Lake Refresh and Panther Lake (PNL-S).

Intel 15th Gen Arrow Lake Desktop CPU Lineup (2024)

The Intel 15th Gen Arrow Lake-S Desktop CPUs will bring back the 24 cores that we get on Raptor Lake CPUs today. The Arrow Lake-S top die will utilize up to 24 cores which will be a combination of 8 Performance Cores and 16 Efficiency Cores.

According to previous leaks, the lineup will only come in Core i7 and Core i9 flavors. The CPU will retain the Intel 4 (CPU) + TSMC N3 (GPU) SKU node layout. It is rumored that the 20A node won’t make its way to the desktop lineup. The Intel Arrow Lake-S Desktop family is expected to come in the following SKUs:

  • Arrow Lake-S 24 (8P + 16E) / 4 Xe Cores / 125W TDP
  • Arrow Lake-S 24 (8P + 16E) / 4 Xe Cores / 65W TDP
  • Arrow Lake-S 24 (8P + 16E) / 4 Xe Cores / 35W TDP

Switching from two families per socket to three families seems to be a good move by Intel to keep the desktop battlefield heated with the competition. It has also worked in favor of the blue team in comparison to AMD. It is also reported that the Royal Cove core architecture which is expected to bring massive performance and IPC increases will not come until the generation after Panther Lake which is expected to be Nova Lake and that’s a 2025+ product.

We know from previous reports that Intel is preparing a new socket known as “V” that will offer support for at least two generations of desktop CPUs, Arrow Lake-S, and its refreshes + future products. This LGA 1851 socket will be very similar in dimensions to the existing LGA 1700/1800 socket but will offer more pins and added support for new/enhanced features.

During its recent investors call, Intel said that they are progressing really well on their Intel 4 & Intel 3 products. The 14th Gen Meteor Lake production stepping is scheduled to be delivered this quarter with a volume ramp in 2023 while Intel 3 is also expected to enter the early production phase by the end of 2023. Do note that these are early charts and we are still years away from the launch of Meteor Lake and Arrow Lake CPUs.

Meteor flashes across early morning sky above Alaska

ANCHORAGE, Alaska (KTUU) – A bright meteor flashed across the early morning sky over Southcentral Alaska Wednesday, according to reports from several residents.

Video sent in from several home security cameras to Alaska’s News Source showed a meteor blazing across the sky above Southcentral at around 5:47 a.m. Wednesday, the winter solstice, when Earth’s northern hemisphere sees its shortest day of the year.

The meteor caused a fireball that ranged in color from blue to orange to white, according to citizen reports from Anchorage and Wasilla, which were submitted to the American Meteor Society’s webpage.

Earth is currently passing through “the dusty material shed by comet 8P/Tuttle, which circles the sun in a 13.6-year orbit and is not due to return until March 2035,” according to Space.com. This annual passage produces what is known as the “Ursid meteor shower.”

According to the website, “The Ursids (sometimes also referred to as the “Umids”) are so named because they appear to fan out from the vicinity of the bright orange star Kochab, in the constellation of Ursa Minor, the Little Bear. Kochab is the brighter of the two outer stars in the bowl of the Little Dipper (the other being Pherkad), that seem to march in a circle like sentries around Polaris, the North Star. The fact that Kochab is positioned so near to the north pole of the sky means that it never sets for most viewers in the Northern Hemisphere. And since the Ursids seem to fan out from this particular region of the sky, means that you can look for these medium-speed meteors all through the night if you care to. The fact that they reach their peak during the overnight hours of Dec. 22-23 is also good news regarding the moon.”

The Ursids bring the last meteor shower of 2022



CNN
 — 

A gift from the skies is coming just in time for the holidays — the Ursids meteor shower. This celestial event will be the last meteor shower of 2022.

The Ursids typically produce only around five to 10 visible meteors an hour, according to EarthSky. While the rates are not as high as other annuals, this year’s shower is set to peak on the night of December 21 with a new moon at only 3% fullness, offering particularly great visibility for people in the Northern Hemisphere, where it will be viewable.

Occasionally, the Ursids have been known to exceed 25 meteors an hour, and even 100 meteors an hour in the years 1945 and 1986. But NASA is not expecting anything out of the ordinary this year, according to Bill Cooke, NASA’s Meteoroid Environment Office lead.

Expert reveals the best way to see a meteor shower

The Ursids shower began on December 13 and will be active until December 24. Still, Cooke suggests viewing the meteor shower close to the night of its peak — if not that night, then the one before or after.

“They’re not terribly faint, but they’re not terribly bright either. The Ursids are a good medium strength meteor shower,” Cooke said. “They’re certainly not the Geminids or Perseids, but hey, if you got time to kill while you’re waiting for Santa, it’s probably a good thing to do.”

The Ursids are often overlooked due to their proximity to the Geminids shower, which peaked December 13 and also can be observed until December 24.

“Meteor observers have historically not spent much time with this one since it falls so close to Christmas,” Cooke said. “Grad students in meteor science used to call them the “Cursed Ursids” because no one wanted to get stuck observing them.”

But any meteor shower can still be an awe-inspiring spectacle. If optimal viewing conditions are enough to entice casual onlookers to brave the cold for a chance to spot an Ursids meteor, Robert Lunsford, fireball report coordinator for the American Meteor Society, recommends watching during the early morning hours of December 22.

“(The Ursids) can be very erratic. I’ve viewed them under perfect conditions and not seen any, and on other times, I’ve seen them outburst at 25 per hour,” Lunsford said. “You don’t know what you’re going to get, but the conditions are almost perfect this year. If you go out to a dark sky, you’ll probably see between five and 10 Ursids per hour.”

The Ursids come from the 8P/Tuttle comet (otherwise known as Tuttle’s Comet), an older comet that does not produce much debris. In the sky, the meteors appear to radiate from the constellation Ursid Minor, more commonly known as the Little Dipper. To differentiate these meteors from the Geminids, viewers should locate the constellation and identify which meteors appear to come from its direction.

“They are visible all night long, because the radiant is very, very far north and never sets,” Lunsford said. “During the evening hours, (the radiant) will only be just a hair over the northern horizon, which means that most of the meteors will be blocked by the horizon, so your best bet is to watch during the last couple hours before dawn.”

The further north you are, the better the visibility for this event, Lunsford said. (For those in the Southern Hemisphere, the shower will not be visible, since the radiant will not rise above the horizon.)

While this shower is the last for the year, sky observers won’t have long to wait for the peak of the Quantrantids meteor display, which will be ringing in the new year just a little belatedly on the night of January 3, 2023.

Look up! The Ursid meteor shower starts tonight (Dec. 17)

The annual Ursid meteor shower will begin on Saturday (Dec. 17) and last through the Yuletide period until the day after Christmas day. 

The Ursid meteor shower will peak on Thursday, Dec. 22, but the following day when the moon is in its fully dark new moon phase might be an opportune time to hunt for bright streaks and fireballs from this meteor shower.

Though at their peak the Ursids can produce around 22 meteors per hour, in dark conditions with little illumination from the moon, skywatchers can realistically expect to see between five and 10 meteors per hour.

The Ursids are often overlooked as a meteor shower for several reasons. First, the shower falls during the holiday season each year, usually occurring between Dec. 13 and Dec. 24, when people tend to have other things on their minds.

Secondly, this meteor shower follows the more flashy Geminid meteor shower and even often intermingles with the peak of this other shower which runs between Dec. 4 and Dec. 20. This year the Geminids peaked on Wednesday, Dec. 14, three days before the Ursids are set begin. 

The best way to see the maximum amount of meteors from any meteor shower is to look for them while the viewing location is pointed at the radiant, and when the radiant is high above the horizon. The higher the radiant is, the more meteors should be visible.

The radiant point of the Ursids is located in the constellation Ursa Minor and for viewers in New York City, this means it is always above the horizon, or “circumpolar,” meaning the Ursids should be visible through the night. 

New York is turned towards the direction of the Ursid meteors at around 8:00 a.m. EST (1300 GMT) this time of year when the radiant point is at its highest. That means when meteors enter Earth’s atmosphere they rain down vertically producing trails close to the radiant and in principle, easier to spot.

Like all meteor showers, the Ursids are created when Earth passes through a cloud of debris left behind by an asteroid or comet as it makes its annual orbit around the sun. This explains why meteor showers occur at around the same time each year. 

As these pieces of debris enter Earth’s atmosphere at high speeds they disintegrate, with the occasional larger pebble-sized debris piece causing a bright flash or a fireball. 

The Ursids are created from debris from comet 8P/Tuttle which jettisons material as it passes close to the sun and radiation from our star transforms solid ice into gas, a process called sublimation. 

Tuttle has an orbit around the sun that lasts around 13.6 years, which is a short orbital period for a comet. 8P/Tuttle is classed as a midsized comet, but still has a diameter of around 2.8 miles (4.5 kilometers). This means it is around the size of the island of Manhattan and is larger than 99% of known asteroids.

It will be a while before 8P/Tuttle is back in proximity to the Earth. Its last close approach was in January 2008, when it came to within around 23 million miles (37 million kilometers) of Earth. It won’t be near as close to our planet again until Dec. 28, 2048, when it will pass us at a distance of around 26 million miles (42 million km).

The year 2130 will be a special one for 8P/Tuttle with the comet passing on Christmas day at a relatively close distance of around 14 million miles (22 million kilometers), over ten times closer to the Earth than the sun is.

The Geminid meteor shower of 2022 peaked tonight (photos)

One of the most spectacular meteor showers of the year peaked tonight and avid skywatchers all over the world were able to capture the spectacle, although some complained that bad weather spoiled their views.

The Geminids are the second richest meteor shower of the year, surpassed only by the August Perseids. A product of debris from the unusual asteroid 3200 Phaethon, the Geminid meteor showers at their peak can produce up to 120 shooting stars per hour. When the sky is clear, skywatchers can catch up to two meteors per minute during the peak, which this year fell on the night of Dec. 13. 

In California, photographer Tayfun Coskun caught some beautiful shooting star streaks above a shipwreck in Point Reyes, a fishing boat skeleton stranded on a sand bar near the small town of Inverness some 40 miles (64 kilometers) northwest of San Francisco. Other skywatchers took their shots against other spectacular backgrounds.

Photographer Paula Corrette shared a mesmerizing snap on Twitter showing a star-studded sky featuring the big reddish spot of Mars and a meteor streak slicing through the photograph right next to it. 

“A little condensation on the lens added a bit of shimmer to Mars as a meteor flew by,” Corrette said in the tweet.

Another photographer, Frankie Lucena, shared a clip showing a bright streak of light crossing the dark sky near Porto Rico’s Lajas Aerostat radar station.

“Geminid meteor near the Lajas Aerostat facing SE from Cabo Rojo, PR,” Lucena tweeted.

A Twitter user called WonderPixel shared footage from two web cameras showing a meteor brightening up the night in Maine. The user said this was the second catch in two consecutive nights. 

“Wow, got another meteor on camera tonight here at http://FreeportMaineWebcam.com. Two days in a row! It’s aiming for Harpswell, and two cams caught it,” the user wrote.

Not everyone who was watching was taking images, but many still enjoyed the show. 

Meteorologist Ed Piotrowski counted 15 meteors in only half an hour and despite less than perfect observing conditions.

“Despite the brightness of the waning gibbous moon and some cirrus clouds, I saw 15 meteors in roughly 30 minutes. Nothing terribly bright though,” Piotrowski tweeted

Many amateur radio operators were able to detect the signal of the space rocks’ passing  through Earth’s atmosphere on their devices, according to ham radio enthusiast and podcaster Bryce Foster.

Some observers, however, were less lucky as clouds obstructed their view. A Detroit-based Twitter user called Delminico Primo said: 

“Looks like Mother Nature is going to block my view of any #Geminids tonite. Was out for a few hours, and had a veiled look at just the brightest objects (Mars, Betelgeuse, and Capella in that first shot), but the clouds are having their way now.”

The same was true for Jon Van Horne in Florida: “Y’all seen any #Geminids tonight from Space Coast, FL?! YA! neither me.” Van Horne said in a tweet accompanied with a picture of a cloudy dusk sky.

The Geminids will continue through Dec. 17, but the frequency of the meteors will drop sharply. The next significant meteor shower will be the Ursids, which will peak around Dec. 22..

Geminid meteor shower fast facts

The annual Geminids Meteor shower is peaking Wednesday morning and will be visible through Dec. 17.

According to NASA, the shower started at or around 9 or 10 p.m. CST on Tuesday and it is expected to peak at 6 a.m. CST on Wednesday. 

Skywatchers can still view Geminids after its peak, but dedicated observers could possibly spot one or two on the night of Dec. 17.

During perfect conditions, the Geminids produce approximately 100 to 150 meteors per hour.

This year, NASA pointed out that a waning gibbous moon would make viewing harder, resulting in just 30 to 40 visible meteors per hour at the peak in the Northern Hemisphere, depending on sky conditions. 

However, the Geminids are bright. 

The fragments travel at 78,000 miles per hour, and most burn up at altitudes between 45 and 55 miles.

The meteors appear to radiate from the constellation Gemini.

Those close to the radiant have very short trails and are easily missed. 

Tracing back the meteor to the constellation can determine if you saw a Geminid. Other weaker showers occur simultaneously.

The Geminids originate from the debris of the asteroid 3200 Phaethon, which orbits the sun every 1.4 years.

 — 

The best chance to see the strongest meteor shower of the year is on its way this week.

The Geminids, known for bright, intensely colored meteors, have been streaking across the night sky since late November, and the shower will peak the night of December 13 through December 14, according to the American Meteor Society.

“If you had to pin one (meteor shower) as being the best of the year, year in and year out, it would be the Geminids,” said Robert Lunsford, fireball report coordinator for the society. “Normally, from let’s say the suburban area, under good conditions, you could probably see 30 to 40 meteors (an hour).”

With clear skies and no bright lights in the way, the Geminids can appear at a rate of about 120 visible meteors an hour, according to NASA. However, there is no escape from the big beacon in the sky that will obscure most of the fainter meteors this year: The moon will be shining at 72% fullness, according to the American Meteor Society.

“It is still going to be a good shower, even with the moon,” said Bill Cooke, lead of NASA’s Meteoroid Environment Office. “Find a decently dark sky, find something that will block the moon, maybe a building or a tree, and look away from the moon at the sky.”

First observed in the mid-1800s, the shower initially delivered only 20 visible meteors per hour at maximum. Since then, the Geminids have reappeared every year, growing stronger in numbers. By the 1960s, the event had surpassed the substantial August Perseids, once the stronger shower with hourly rates of 50 to 100 meteors.

It is unclear how the Geminids might change in the foreseeable future, Cooke said, with some models indicating the shower will increase in intensity and others estimating a gradual decline over the next few decades.

The Geminids are unique in that their source is the asteroid 3200 Phaethon, while most other meteor showers are born out of debris from icy comets. That’s why Geminids streams can be unpredictable — because it is more difficult to model asteroid breakups, Cooke said.

The asteroid 3200 Phaethon is unusual in its own right, behaving like a comet when it nears the sun. It also has an orbit, which it completes every 1.4 years or so, that’s closer to the sun than any other asteroid. When 3200 Phaethon is near Earth, the asteroid sheds its dusty debris, hence the Geminids display.

The Geminids are active from November 19 to December 24, according to EarthSky, but their hourly rates don’t start reaching double digits until December 10, Lunsford said.

The shower is known for being family friendly and a good one for young viewers in North America to observe since it’s the only major shower that exhibits the most activity before midnight. The meteors appear to radiate from the constellation Gemini, which will rise in the sky at around 10 p.m. ET, Lunsford said.

“You can observe when the radiant is at its highest, which is between 1 a.m. and 2 (a.m. ET) with moonlight, or you can try viewing earlier in the evening when the moon is still below the horizon,” Lunsford said. “The rates will probably be fairly similar at those times, too.”

The Geminids will be viewable from all parts of the world, but for the Southern Hemisphere, it is best to view toward the middle of the night at 2 a.m. local time, since the radiant will need to be at its highest to be seen. The position of the radiant will be low on the horizon and will also cause the meteors to appear at a reduced rate, Lunsford said.

According to NASA’s meteor camera data, the Geminids shower is among the best for production of fireballs, meteors that are brighter than the planet Venus, second only to the Perseids, Cooke said. The biggest and brightest Geminids meteors are often said to appear greenish in color.

The moon’s Illumination has affected Geminids watching for the past two years, but the meteor shower is expected to occur around a new moon in 2023, creating perfect viewing conditions.

“When you see a meteor burn up in Earth’s atmosphere, you’re seeing something that’s been out in space for a very long time,” Cooke said. “From a scientific perspective, by studying it, we can learn something about what makes up those comets. To the casual observer, they’re a nice firework (display) — meteor showers are nature’s fireworks.”

The next and final major annual meteor shower of 2022 will be the Ursids, which peak the evening of December 22, according to EarthSky.

Two meteor showers to brighten the December sky. Here’s how to see the shooting stars.

Two meteor showers will be gracing the night sky in December, including one that is known for producing lots of bright shooting stars.

The first one on tap is the Geminid meteor shower, and it will be followed by a late-month meteor shower known as the Ursids.

When to see the Geminid meteor shower

The annual Geminid meteor shower often produces 50 to 100 meteors per hour and even as many as 120 per hour in dark locations during its peak period of activity.

Although this meteor shower started in late November and will last through Christmas Eve this year, the Geminids are expected to be at their best during the evening hours on Tuesday, Dec. 13, into the early-morning hours on Wednesday, Dec. 14, according to astronomy experts at EarthSky.org.

Because the December moon will be about 75% full, it will likely be tough to see the faintest meteors. But experts say the Geminids are known to produce meteors that are white and bright, so many should be visible this year.

While most meteor showers originate from comets, the Geminids are actually small fragments of an asteroid, known as 3200 Phaethon. (Another meteor shower that’s linked to an asteroid is the Quadrantids, peaking in early January.)

The Geminids were named after the constellation Gemini, “because the meteors seem to emerge from this constellation in the sky,” says TimeAndDate.com.

When to see the Ursid meteor shower

The final meteor shower of 2022 will be the Ursid meteor shower, which will be visible in the northern hemisphere from Dec. 17 through Dec. 26 and will likely reach its peak during the late-night hours of Dec. 22 into the early morning hours on Dec. 23.

“Visibility should be good for the 2022 Ursid meteor shower,” Space.com says. “The sky will be void of bright moonlight, as the new moon arrives on Dec. 23.”

The Ursid meteor shower usually generates only five to 10 shooting stars per hour, with the highest numbers in the darkest locations. However, once in a while, this meteor shower over-performs.

Viewing tips for meteor showers

As with any meteor shower, it’s best to find a viewing location that is as far away as possible from bright city lights or street lights. And make sure you bundle up and bring extra blankets if the weather in your area is cold.

Give your eyes about 20 minutes to adjust to the dark sky.

Even though meteor showers get their names from the constellation where they radiate from, astronomy experts say it’s best to not focus on those parts of the sky.

“You don’t want to look towards these constellations to see the meteors, but all around the sky,” said Amie Gallagher, planetarium director at Raritan Valley Community College and secretary for the Middle Atlantic Planetarium Society.

“You don’t need to use a telescope or binoculars to watch a meteor shower,” Gallagher noted. “Just use your eyes and scan the sky.” She said the timing of your viewing also makes a difference in the number of shooting stars you can spot.

“Meteor showers are best watched after midnight,” Gallagher said. “That’s when the part of the Earth that you are on is moving into the stream of debris in space left behind by the parent comet.”

However, with this year’s Geminid meteor shower, the bright moonlight might interfere with visibility during the late-night hours and after midnight. Because of that, Gallagher says, “you might have better luck looking for meteors in the evening, before the moon rises.”

In the New York City region, the moon is scheduled to start rising at about 9:30 p.m. on Dec. 13 and about 10:30 p.m. on Dec. 14, according to TimeAndDate.com.
