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 SkyThe 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 AquariusTime 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.

Meteor Shower

Of course people will be watching fireworks in person or on TV the night when Dec. 31, 2021 turn into early morning Jan 1, 2022.

But the sky will be doing its own show during this period with the Quadrantids. They will peak when Jan 3 turns to Jan. 4, 2022.

The good news is that the New Moon will rise and set with the Sun so it won’t be a factor.

The sort of bad news is that the meteor shower peak of about 110 to 120 meteors an hour is a short couple of hours. The expected peak time is 21 UTC (Universal Time Clock.

Named for a defunct constellation Quadrans Muralis the meteor shower’s other name is the Bootids for constellation Bootes. The parent is Asteroid 2003 EH which takes about 5.5 years to orbit the Sun.

The Perseid meteor shower is back

Put August 11 on your calendar to watch the night sky. The best meteor shower of the year, the Perseids, will be entertaining night sky watchers with at least  40 fireballs an hour when they peak next week. However, they have been known to rack up as many as 100 meteors per hour.

As debris from comet Swift-Tuttle, the Perseid Meteor Shower occurs  annually when earth’s orbit takes it near the comet’s path from the end of July to mid-August. The meteors are already zooming across the sky but in 2021 the peak is Aug. 11-13.

If you like company or have trouble seeing them, tune into NASA which has invited everyone to watch with them. Watch time is Aug. 11-12 from 10 p.m. to 5 a.m. CDT on FacebookTwitter and YouTube.

If weather is a problem,  there is likely to be a second chance Aug. 12-13. The livestream is hosted by the Meteoroid Environment Office at NASA’s Marshall Space Flight Center.

A crescent moon will be setting early so moonlight shouldn’t be a factor. Watch between midnight and  dawn away from city lights. Some folks  stretch out on blankets but if the ground is dewy damp pull out a lawn chair.

Don’t worry if you don’t see any meteors right away. It takes a few minutes to adapt to the night sky. The meteor shower radiant appears to be above Perseus.

Meteorites skim planet Earth this week

The Eta Aquarids, the first half of Halley’s Comet’s two rounds of meteor showers, peak May 4-6, 2021. The two meteor showers are debris from Comet Halley as Earth  passes through the comet’s path around the Sun.

Seen in both hemispheres, the Southern Hemisphere arguably offers a better view now when its radiant, the Aquarius constellation, is overhead and Northern is better for its second round, the Orionids, in October. But both meteor showers are popular with sky watchers.

After acclimating your sight to the night, look in the southern sky for Eta Aquarii, the constellation’s brightest star. Depending on the weather, you may be treated to more than 30 meteorites per hour.

The moon, now in its waning crescent phase should not be a factor, particularly if watching for the meteorites early on May 6 before dawn.
