Video — from the UW Atmospheric and Oceanic Sciences rooftop — of a bright meteor at 11:50 PM CST Monday night.

This is a view looking up University Avenue toward the state capitol:

Original Mike म्हणाले...: Yeah, that's a pretty good one. Late for a Geminid, but ii is coming from the right direction.; २०/१२/१७, १०:०७ AM
Wince म्हणाले...: Unfortunately, you can't find at least three "wise men" among the entire UW faculty.

And if you did it'd be misogynistic.; २०/१२/१७, १०:०८ AM
Curious George म्हणाले...: God missed.; २०/१२/१७, १०:०८ AM
Nonapod म्हणाले...: Apparently the Earth accumulates about 60 tons of cosmic debris every day. If that's true though, it means the Earth has gotten bigger over the past 4.5 billion years. I mean, I assume that very explosive volcanoes may occasionally eject a small amounts of material out of the Earth's atmosphere, but the overall net amount wouldn't offset the gain I imagine.; २०/१२/१७, १०:०९ AM

Not since I retired.; २०/१२/१७, १०:१० AM
Jaq म्हणाले...: I just saw a really cool one last night too, over Florida. It broke in half before the two pieces faded out. In Miami last year, I saw one that was very bright, and must have contained copper, because it glowed green.; २०/१२/१७, १०:१९ AM
Jaq म्हणाले...: The one I saw was at about the same time, BTW.; २०/१२/१७, १०:२० AM

You get different colors based on the excitation of atmospheric components.. Green is very common for meteors. I've seen it a lot (though it takes a bright meteor.); २०/१२/१७, १०:२६ AM
rhhardin म्हणाले...: It's caused by accumulations of gasses in the upper atmosphere.; २०/१२/१७, १०:५० AM

Bright enough to attract all of our attention over the well-lit Miami skyline. It was probably up there tops with any I have seen. My coolest one though was on a rainy night, when it came down through the clouds and fog. It looked like an extremely bright blue-white street light had been thrown through the sky.; २०/१२/१७, ११:०९ AM
Char Char Binks, Esq. म्हणाले...: I saw it as it happened.; २०/१२/१७, १२:२० PM
traditionalguy म्हणाले...: Hmm. A Space War battle also results in the splashing of many enemy satellites.; २०/१२/१७, १२:५९ PM
LYNNDH म्हणाले...: That was no meteor, it was Aliens it tell you. ALIENS!
Either that or the exploding heads of Democrats' over the Tax Bill passage.; २०/१२/१७, १:०१ PM
David म्हणाले...: A little hint about human mortality.; २०/१२/१७, १:५० PM
Owen म्हणाले...: At what altitude would it have flared and then (presumably) exploded into little bits? What was its mass? Do we want to worry about these fellows hitting the ground, causing sonic booms, etc?; २०/१२/१७, २:३६ PM
eddie willers म्हणाले...: I was standing on my back porch in NE Georgia at dusk when I saw the most magnificent green bolide I had ever seen going northward.

Being pre-Internet, I kept checking the paper until I saw an article about a meteorite hitting a car.

Today it is known as the Peekskill meteorite. The car is going to Paris .; २०/१२/१७, २:४० PM

Apparently the Earth accumulates about 60 tons of cosmic debris every day.

On the other hand, we are leaking gasses at the same time.; २०/१२/१७, २:५० PM
MadisonMan म्हणाले...: Either that or the exploding heads of Democrats' over the Tax Bill passage

The tax bill passed overnight today. The meteor occurred 2 nights ago.; २०/१२/१७, ३:०० PM
Kyzer SoSay म्हणाले...: Wifey and I saw a bright green meteor last October over Columbus Day weekend while driving south along Rt.42 in Door County, WI. It was magnificent. Appeared to be heading south over Green Bay, and we were lucky to see it given how many trees were potentially in the way.; २०/१२/१७, ३:१२ PM
Quaestor म्हणाले...: Apparently, the Earth accumulates about 60 tons of cosmic debris every day. If that's true though, it means the Earth has gotten bigger over the past 4.5 billion years.

Helium as a nuclear decay product is leeching up through the crust constantly (too bad for balloons and airship dreams). And many chemical reactions release Hydrogen, so that's being constantly lost to space as well, thus the accumulation of meteorite material gets offset to some degree.; २०/१२/१७, ५:१५ PM
Quaestor म्हणाले...: The Moon is probably growing faster than Earth. Good thing it's receding else things could get nasty eventually.; २०/१२/१७, ५:१८ PM
