Hello all-- I have been watching satellites this summer with my son Matt (8) ever since the shuttle/MIR linked up and were easily visible over Boston. I heard about the list from Ted Molczan's notes attached to his elements. I am more of a computer expert than an orbital expert; I run Linux rather than MS-DOS/Windows although the DOS emulator of Linux lets me run most of the DOS prediction software I have tried. With Linux, I can do something else while my predictions run, although it seems Mike McCant's quicksat lives up to its name. Obs of the month (so far): 10820 (DMSP B5D1-3), 10 Oct 95, tumbling, too dim to see between flashes. Counted about a 14 sec interval between flashes, then 10 seconds until a brighter flash. Evidently a complex motion. Tim Wallace 3 Hilda Rd. Bedford, MA 01730
