Sky watch meteors and full moon

New Year’s Eve fireworks kept sky watchers engrossed as TV stations moved across the world to different time zones and countries Dec. 31, 2022.

Then nature followed with the Quadrantids meteors. Begun Dec. 28, it peaks pre-dawn Jan. 3 to Jan 4 in 2023. Their “parent” is the Asteroid 2003 EH from the defunct constellation Quadrans Mualis.

They seem to radiate from a point east of Ursa Minor (The Little Dipper) but can be seen anywhere in a clear sky. The problem will be the moon which will be waxing gibbous on its way to full illumination Jan. 6.

For best time to watch and where in your region check TimeandDate Quadrantids.

Next looking up, is a Mircromoon. Called the Wolf Moon, January’s full moon is considered a Micromoon because it appears smaller due to its orbit which takes it far from Earth (as opposed to a Supermoon which appears large because it is close to Earth).

The January 2023 full moon reaches full illumination at 5 p.m. CST Jan. 6, but will appear full the day before and day after. Some Native Tribes have called it the Wolf Moon because wolves tend to howl more in January.

Read more about the January moon’s names in The Old Farmer’s Almanac.

Look between the snowflakes for the Ursid meteors

By now you probably heard that the Northern Hemisphere’s Winter Solstice of Dec. 21, 2022, will be making itself known Wednesday followed on Dec. 22-23 by very cold temps, blowing winds and more snow than folks need for a white Christmas.

So, it might be challenging to see the Urid meteors flying across the sky when they peak in the very early hours Thursday and Friday. The good news is that the moon is in its darkest waning crescent phase with very little illumination and becomes a new moon with no illumination Dec. 23.

The Urids are so named because they seem to radiate from the constellation Ursa Minor (the Little Dipper). Their parent is the 8P/Tuttle comet. They started Dec. 13 and continue through Dec. 24.

Producing only five to 10 meteors an hour, the Urids are a comparatively minor meteor shower but it’s always fun to “catch” a meteor.

It is not a Halloween trick or an alien ship

You don’t have to call a government agency or a news station if you see a fireball overhead. It’s not a trick. It’s a treat. The Taurid meteors are charging across the sky.

However, you might want to notify the American Meteor Society because that organization does keep track of fireball sightings and does want to hear about them.

Indeed, a sighting is likely in 2022 because AMS says the Taurids last great meteor production was in 2015. Taurids’ history has shown that its abundant output tends to happen every seven years.

BTW, other years it’s not so great. So, the time span might be why you hadn’t heard about the Taurids before.

The meteors seem to emanate from constellation Taurus the Bull (its radiant) in two streams, the North and South Taurids. In 2022, South peaks Nov. 4-5 with North peaking Nov. 11-13. Taurus the Bull is near the constellation Orion.

A better watching is arguably period now through Halloween and Day of the Dead. The moon cycle reaches its full stage Nov. 8 so its growing illumination period may make it harder to catch a fireball on Nov. 5. But fireballs, like their name, are bright, so maybe try the peak date.

The Taurids already started Sept. 10 and continue through Nov. 20, 2022. As with most other meteor events, they happen when Earth passes through a stream of cometary debris. With the Taurids that is what Comet 2P-Encke, the parent comet, leaves behind, according to NASA.

NASA notes that unlike many comets, 2P-Encke is not named for its discoverer, Pierre F. A. Mechain, but for Johann Franz Encke who calculated its orbit. The letter P means it is a periodic comet.

Whatever dates you venture out to see a Taurid meteor, the best time is after midnight when the radiant is high. But dress warmly and be prepared to wait. Best watching technique is to scan the skies instead of focusing on the Taurus radiant.

Sky show this week

Look up after midnight to watch what is among the year’s best meteor shower.

Those meteors zooming across the sky at about 41 miles per second are the Orionids. Although they started the end of September and go through mid-November the best time to “catch a falling star” as the song goes, is during the shower’s peak of Oct. 21 when you may see between 10 to 20 meteors per hour.

Fortunately, the moon will be merely a slim wanning crescent during the peak date so moonlight won’t be a factor to see the sky show. Because the Orionids often leave bright trains and show-off as bright fireballs, sky watchers are likely to be rewarded with a meteor or two.

Where they seem to come from is called the Radiant so with a name like Orionids, expect to look towards the Club of the Orion the Hunter constellation. Look north of Orion’s bright Betelgeuse star.

The Parent (origination) of the Orionids is 1P/Halley. Right, the comet. These meteors are comet debris. Dust of Halley’s Comet produce the Eta Aquarids in May, usually best seen in the southern hemisphere, and the Orionids which are better, brighter and can be seen in both hemispheres in mid-October.

Note: Dress warmly and be patient. The meteor show goes from midnight until dawn.

Meteors and Supermoon compete for attention

Circle Saturday, Aug. 13, 2022 on the calendar or make a note on the smart phone for a double sky phenomenon. But one sky event may make it hard to see the other.

The Perseids, arguably the best meteor shower of the year, already started July 17 but continues through Aug. 24. It peaks Aug. 12-13 with from 50 to 100 meteors zooming across the sky per hour.

The meteors are debris from parent comet 109P/Swift-Tuttle whose radiant is the Perseus constellation in the northeastern sky. The greatest number of meteors will be visible after the radiant rises, according to Earth Sky. The radiant rises around 11 p.m. CT, nearly due northeast in Perseus so the Perseids are best viewed from midnight to sunrise.

Perseus was the Greek mythological hero who stopped (beheaded) Medusa the Gorgon (Maybe you’ve seen the TV ad where Medusa enters a bar and turns guys to stone).

The problem: August’s full moon, glowing in the sky Aug. 11-13 is the fourth and last supermoon of 2022. As a supermoon whose orbit brings it closer to earth than most moons come the rest of the year, it looks larger and brighter than usual. That large illumination makes it harder to spot meteors.

“Sadly, this year’s Perseids peak will see the worst possible circumstances for spotters,” said NASA astronomer Bill Cooke, who leads the Meteoroid Environment Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

“Most of us in North America would normally see 50 or 60 meteors per hour,” he said, “but this year, during the normal peak, the full Moon will reduce that to 10-20 per hour at best,” said Cooke.

Aptly named, at least for 2022’s August Supermoon, this full moon is called the Sturgeon Moon after the giant fish found in the Great Lakes that is often caught the last month of summer. A good source for full moon names is The Old Farmer’s Almanac. The sturgeon is considered a “living fossil” for its beginnings about 136 million years ago.

Meteors overhead

Word of meteor sightings in the middle of July have been coming into news bureaus but little has been said about the timing. Astronomers know there is usually meteor activity going on over head.

However, the meteor showers that catch attention are typically the big ones with major peak times such as the Perseids that peak Aug. 11-12 in 2022.

Peak dates don’t mean those meteor showers haven’t already started.

Currently the Delta Aquarids which are a montage of meteors seeming to radiate below the “square” of Pegasus, started about July 18 and go through early August. They can produce up to 20 meteors per hour.

Their best sighting is from mid-evening to dawn in the Southern Hemisphere and the southern part of the United States during the new moon phase July 28. That is when moonlight won’t be a factor because the moon is between Earth and the Sun.

In addition, the Perseids have also started. Brighter than the Delta Aquarids, they can be seen now because the comet of origin, 109P/Swift-Tuttle, passes through Earth’s orbit July 14 to Aug. 24. Their peak will be during August’s full moon phase Aug. 12 but is expected to deliver about 100 meteors per hour.

So, just because a meteor shower is said to peak at a certain time during the month, does not mean its meteors aren’t zooming overhead before and after those dates.

EarthSky has a good analysis of these two July-August meteor showers.

Tau Herculids meteor shower

Back in the beginning of May we mentioned two meteor showers for the month: the Eta Aquarida early in May and the Tau Herculids at the end of May.

What was unknown and only a guess was how large the Tau Herculids shower would be. It wasn’t on everyone’s radar as one to watch or even existing.

However, EarthSky suggested it could be an exciting display because it was the debris from parent comet 73P/Schwassmann-Wachmann 3, (SW3) which had been breaking up and would likely be seen in the Earth’s Western Hemisphere at night

Though the debris was, as predicted, not bright, and didn’t fill the sky with hundreds of meteors at a time, the Tau Herculids did put on a reasonable display with as many as 25 to 35 meteors seen around midnight CT May 30 p.m. to May 31 a.m.

Noticed by astronomers in 1930, it is now on more sky watch lists. A good site to see reports of the meteor shower is at EarthSky.

May meteor watch now and end of month

May is continuing to be a month to watch the night skies.

The Eta Aquarid Meteor shower from 1P/Halley that started in April is peaking May 4-6. Between 30 to 50 meteors per hour are expected in the pre-dawn hours. Although they are more visible in the southern hemisphere because their radiant is the southern constellation Aquarius, Time and Date suggests watching for them about 3 a.m. CDT.

Late in the month, May 30-31, watch for a somewhat more recently-known meteor shower, the Tau Herculids. EarthSky suggests it may be an exciting display this year.

Coming from the parent comet 73P/Schwassmann-Wachmann 3, (SW3), it was noticed by astronomers in 1930. Although not bright, it keeps breaking up and has a large amount of debris.

If the weather doesn’t co-operate or you miss either meteor shower and want to know when others are still coming in 2022 visit the Old Farmer’s Almanac Meteor Calendar. It has good-to-know dates and information.

Eyes up for the Lyrids

Now that April’s full moon is starting to wane moonlight will hopefully not interfere with April’s meteor shower: the Lyrids.

Known for how bright they are and fast they fly across the sky leaving glowing trails of dust, they already began on April 16, but they peak between April 21-23 with between 15 to 20 meteors per hour.

The Lyrids, called that because they seem to come from the constellation Lyra, were first recorded by the Chinese in 687 BC, making them the oldest known meteor shower.

What observers see is debris from the C/1861 G1 Thatcher comet in both the Northern and Southern Hemispheres as the comet’s orbit crosses those skies in mid-late April.

Best time to watch is predawn when the moon has set and the sky is still dark. If watching for them, give your eyes a chance to adjust to the night sky and find a spot away from street and highway lights and businesses.

Best meteor shower

“Catch a falling star.” That idea shouldn’t be hard the first half of December when the Geminids send about 120 meteors per hour across the sky at its peak.

Although most meteor showers happen when the Earth passes through the debris from comets, the Gemeni meteor shower is debris left by an asteroid called 32 Phaethon.

However, the Geminids, as the shower’s meteors are known, are named for their radiant point in the constellation Gemini where the “Twins,” the bright stars Castor and Pollux, reside. They appear to emanate from Castor which can be found near Pollux.

But this meteor shower can be seen from all directions so don’t worry if you can’t pinpoint the constellation.

The Geminids, considered among the best meteor showers of the year, starts Dec. 3 in 2021. To catch it at its peak, look up the night of Dec. 13 into the early hours of Dec. 14.

Of course, the best viewing area would be away from city and street lights.
