Dear Seesat'ers, I just saw my first daytime Iridium flare! The sun was 16 degrees above the horizon. It lasted less than one second and was much brighter than Venus (the mirror angle was 0.25). If I hadn't know what it was I might have thought that an unseen airplane had produced it. The sky is unusually transparent today. Randy Iridium 14 10-Mar-1998 0:41:41
