Lyrid Meteor Shower and the dust of Comet Thatcher

SpaceWeather.com is one of my go-to sources for information about what’s going on up there, and they explain that what’s going TONIGHT is the peak of the annual Lyrid Meteor Shower:

Every year in late April Earth passes through the dusty tail of Comet Thatcher (C/1861 G1, named by A.E. Thatcher in 1861), and the encounter causes a meteor shower–the Lyrids. This year the shower peaks on Saturday night, April 21st. Forecasters expect 10 to 20 meteors per hour, although outbursts as high as 100 meteors per hour are possible.

Lyrid meteors appear to stream from the bright star Vega in the constellation Lyra. In fact, Lyrids have nothing to do with Vega. The true source of the shower is Comet Thatcher. Every year in April, Earth plows through Thatcher’s dusty tail. Flakes of comet dust, most no bigger than grains of sand, strike Earth’s atmosphere traveling 49 km/s (110,000 mph) and disintegrate as streaks of light.

Lyrid meteors are typically as bright as the stars in the Big Dipper, which is to say of middling brightness. But some are more intense, even brighter than Venus. These “Lyrid fireballs” cast shadows for a split second and leave behind smokey debris trails that linger for minutes. Occasionally, the shower intensifies. Most years in April there are no more than 5 to 20 meteors per hour during the shower’s peak. But sometimes, when Earth glides through an unusually dense clump of comet debris, the rate increases.

Our friends at EarthSky share that the pre-dawn hours of April 22nd are best to see the Lyrid Meteor Shower & they also have info about catching a last glimpse of Comet Panstarrs.

Daniel took this photo back in April of 2013 and shares “I went out in an attempt to catch some meteors from the Lyrid Meteor shower. I was very unlucky and didn’t catch any. My methodology for shooting the meteors is to just find a composition and set it up to take as many 30 second exposures that I am willing to wait through. In this case, 182 exposures. This way if I don’t catch a meteor, I still get some star trails to show off.” See more in his Moon & Stars gallery on Flickr and view & purchase his work on his website.

Lyrid Meteor Shower AND Northern Lights this weekend!!

I got an alert this morning that the Kp levels that predict the likelihood of northern lights is at 5 to 6 over the next two nights making the aurora a strong possibility for much of Michigan. Lots about the northern lights on Michigan in Pictures.

Now let’s add into the mix the annual Lyrid Meteor Shower. It’s a more variable shower than the Perseid or Leonid showers, but it has still produced some impressive showers in the past AND we are blessed with a waxing moon that will make viewing a lot better. EarthSky shares:

The annual Lyrid meteor shower peaks this weekend! It’s active each year from about April 16 to 25. In 2018, the peak of this shower – which tends to come in a burst and usually lasts for less than a day – is expected to fall on the morning of April 22, with little or no interference from the waxing moon.

No matter where you are on Earth, expect the greatest number of meteors to fall during the few hours before dawn.

In a moonless sky, you might see from about 10 to 20 Lyrid meteors an hour at the shower’s peak on the morning of April 22. In 2018, the waxing moon will set before the primetime morning hours. An outburst of Lyrid meteors is always a possibility, too, though no Lyrid outburst is predicted for 2018.

In 1982, American observers did see an outburst of nearly 100 Lyrid meteors per hour. Around 100 meteors per hour were seen in Greece in 1922 and from Japan in 1945.

Ken writes that (back in April of 2016) he shot over a 3 hour period in hopes to catch the meteor ‘shower’ and only caught this one streaker. View his photo bigger, see more in his Skies Above album, and visit Ken Scott Photography to view & purchase work!
