I checked el970706 down to mag.+8 according to SkyMap ( range <4444 km and perigee <2222 km ) and found nothing better. As I often do, I'd like to stress that it would help identification to have an estimate of apparent speed, and direction relative to vertical (or to a line between stars), at a point on the track, as a complement or even instead of general large-scale motion. This would make sure that the risk of ignoring distant objects, or incorrectly picking a low one, is reduced. Magnitude estimate, and flash period, can of course also help experienced observers, or when comparing to magnitude/PPAS data. ------------------------------------------------------------ -- b_gimle@algonet.se +46-8-7428086 (home) -- -- 59.22371 N, 18.22857 E AND member of : -- -- http://www.algonet.se/~b_gimle SeeSat-L -- -- bjorn@tt-tech.se +46-8-59095783 (office)-- ------------------------------------------------------------
