Was just outside with the roomate and we wintnessed something in the sky we couldn't explain. It didn't move and had incredibly bright lights. The lights were flashing red-blue-red-blue-red-blue. It stayed in the same place for the 20 minutes that we were out there for. Here's the best part: I got pictures. The pictures make this experience that much weirder... Pics and vid to come.

I dont know if its a type of metal or gas that makes them green but ive seen one myself.

I don't believe there is much evidence to support the idea that meteor
color (as seen with the eye) has much relationship to the meteoroid
composition- at least, when we are talking about fireballs. There is good evidence, however, that the color is mainly the from ionization of atmospheric gas- especially oxygen. I've personally collected images of
several bright fireballs through a 501 nm narrow band (6 nm) filter,
which argues for a very strong [OIII] component to the light.
FWIW, a quick review of the meteor reports (nearly all fireballs) I've
received in the last 11 years shows this:
9110 reports total
3735 (41%) report some sort of color
3069 (82% of those reporting color) report some shade of green
I've long since concluded that bright fireballs are almost always green.
The exceptional cases are those which are not (and these are almost
always reported as white).
The only other color that tends to show up in witness descriptions is
red/orange, and a close look reveals that this is almost always at the
end of the path, when it is easily explained as the output of a cooling

I think no two people perceive color exactly the same. We grow up being told
various objects, etc. are certain colors and we learn that, even tho each person
may not be seeing exactly the same tones, hues, etc. My parents once owned a
car that to my eyes was "dark blue" or at the very greenest "very slightly
greenish dark blue"; but my mother and my sister insisted that the car was
Some of this is also noticed when observing double stars - even when they are
far enough apart that one star can be gotten out of the telescope's field of
view - so as to not have the contrast effect "messing up" the color
determination. If there are only three or four people this can be an
interesting project observing double stars and each person writing down the
colors they see without comment and then after all have viewed a particular pair
comparing the results; also later comparing the results with published sources.
I have observed around 40,000 meteors. Of these fewer than 5 were truly green.
The brightest was a mag. -3 Geminid. Fairly bright shower fireballs often start
out yellow or orange, but at peak brightness are usually white. I have seen
quite a few fireballs in the mag -4 to mag -8 range that I would describe as
very pale blue, blue-white, or pale greenish blue (these often starting out
yellow or orange). I once observed the Perseids with a person who said most of
the bright Perseids were green. To me the same meteors were either white or
One of the most beautiful meteors I ever saw was a South Taurid in late
September which was a scintillating ball of blue-white sparkles (like the
"flare" from a very bright object, such as a welder's torch) nearly as big as
the Moon with an orange wake several degrees long - magnitude probably -12 ?)
As for red meteors - I have seen only 5 or 6 that I would call truly red - but a
fair number of red-orange or deep orange meteors. (We must remember that many
persons call Arcturus and Aldeberan red stars - tho they are actually more
orange.) The brightest and slowest sporadics I have seen were all yellow or
orange or deep orange thruout their paths (mag -8 to mag -12).
I have not seen many truly blue meteors.
