In recent years, its flash period typically was about 8.7 s, but there seemed to be a slow long-term trend toward a shorter period." Just to fine-tune. It has been observed at mag +4 at apogee (40,000 km?). It has done very bright flashes on perigee passes (less than 10,000 km in range, if memory serves). Also, I reported it flashing every 6.5 seconds last month: http://www.satobs.org/seesat/Sep-2010/0173.html I've seen it at least one other night recently. Jay Respler first reported it to this list in 1997, but it became famous after being spotted by an commercial aircraft pilot and an astronomer on the same night, events analyzed in a post by Mike McCants: http://www.satobs.org/seesat/Mar-1998/0070.html Here's the pilot's original report: http://www.satobs.org/seesat/Mar-1998/0064.html Ed Cannon - Austin, Texas, USA _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
