If you have clear skies and can watch after midnight, chances are good that you can catch way more than one “falling ” star this weekend.
The bright, prolific Perseids, will be shooting debris from the 109P/ Swift- Tuttle comet at 90 or more meteors per hour late at night, Aug. 11-13 and peaking Aug. the 13th. The moon is a waning crescent so shouldn’t be a light factor.
They already started in mid-July and continue until Sept 1 but this weekend is expected to be their biggest display.
They are fun to watch as they are fast (37 miles per second) and are streaks of light with long trains or “wakes.” Plus, they are usually colorful.
Best time to look is very, very early in the morning before the sun rises. They shoot all over the sky but the radiant (where they seem to come from) is the northern section of constellation Perseus which is higher in the sky shortly before dawn.

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.

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 Facebook, Twitter 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.
Check the weather predictions in your area for Aug. 11-13. That is when the Perseids are supposed to be peaking with bright meteors shooting across the sky at 50 to 100 an hour.
Best time say the experts, is in the northern hemisphere right before dawn, so also check the sunrise times for your area.
Because these meteors are bright, plentiful and have long tails, the largish waning crescent moon might not be much of a hindrance the night of Aug. 11. By Aug 13 the moon will be thinner though there may be fewer meteors.to spot.
So where do they come from?
The Perseids are debris from the 109P/Swift-Tuttle comet. They are called Perseids because they look like they emanate (their radiant) from the Perseus constellation as the Earth moves through their trail each summer.
The comet’s name comes from Lewis Swift and Horace Tuttle who discovered it in 1862.
