Hi Marco and list, This spacecraft seems to produce short flares at least once at almost every pass. I saw one myself on Sept. 13 at about 00:02:10 UTC that lasted about 2 seconds with a magnitude of -2 to -3 and someone on my Obsat list photographed one on Sept. 11 : http://img10.imageshack.us/img10/4540/2htv.jpg We see the short flare on the otherwise faint horizontal trail on that picture. I don't know if the spacecraft is in a barbecue mode or is in a stable mode. If it is stable, these flares must come from a reflective flat surface or something similar and should be predictable.

It flared once, at about 19:28:35 UTC, to mag. -2. Had bad luck with the pictures though: flare happened inbetween two exposures, and the images turned out a tad unsharp (was using another lens than usual to get a wider FOV because of the fast movement of the HTV). - Marco ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
