Cool, I'll have to look into that. Thanks for the heads up =) As an aside, several weeks back I spotted this very bright circular (white) light in the SSW night sky (12:50am PST, 60 degree azimuth). Like a gigantic spotlight in the sky, shining straight down to Earth. Had a duration of about 5 seconds or so, and then disappeared as quickly as it formed. Then a week and a half later, same thing. Did some research, and it turned out that it was what is called a Iridium Flare (solar relection off of one of the Motorola Iridium telecommunication satellites). Both were mag -8 (as reference, full moon is around mag -12.0 to -12.5) - more negative the number, brighter the object. Very, very cool! What are the odds are that I'd look at the night sky at the precise time, and at the right area? And to see the brightest flares, twice by pure stroke of luck. It's like I won the celestial lottery. Turns out that you can predict when and where they occur for your location (see http://www.heavens-above.com/). Not surprising given that satellites travel in precise orbits. Now on the occaison I schedule times to go out to see the flares (but only the mag -7 and -8's). Also, there are daytime flares as well - although the nightime ones are, for the obvious reasons, more spectular. I know you have all seen satellites crossing the nightsky, but a mag -6 to -8 Iridium Flare kicks you know what!
