Hello! This is my first post to this list but some of you may already know me from sci.astro.satellites.visual-observe newsgroup. I've been reading the List archives on the Web recently and thought I could try answering one question.

Now that I think about > it, I think I was mistaken. Can anyone confirm? Here is the map I've just generated from my archives of Iridium flares: http://hea.iki.rssi.ru/~denis/Iridmap2000.gif As you can see, flare positions cover almost the whole sky more or less uniformly. Map is centered at R.A.=12h00 (180 deg), Decl.=0 deg. There's a gap near the center (in the constellation of Leo), but exactly these days we're having flares in that very area of the sky. Moments are calculated for the point in Moscow with lat=55o45', long=37o37'. If I dig up a little more in my archives, I will probably find visible pass chart of a flare within 2 (?) degrees from the Moon. Don't remember the date right off. Den -- Denis Denissenko, M.Sci.
