I'll be happy to cover that bit, but only up to the amount you can afford to lose. I think G3RUH says it will re-enter on the night side because the orbit will still be quite elliptical when it finally re-enters. Since the apogee side of the ellipse will be pointed at the sun next December, the perigee side will be on the night side of the planet. I think it's safe to assume that the last orbit will finish with a perigee that turns into a fireball. By the way, I forgot to mention that G3RUH will be posting new, updated keps very frequently as the orbit starts to decay. That and the near guaranteed night time reentry makes this a good one to watch for. The satellite is a meter or two across and weighs a hundred kilos or so. ftp.amsat.org/amsat/satinfo/ao13/decaykep.zip Dave, N9LTD
