However I dont think Highfly.mag has been updated since AO-40 was launched, so thats no good. A check of the data from WSRN suggests a 2 sq metre object has a magnitude at 1000 miles of mag 7.0 or so, so at a rangle of 60,000Km it would be about 8.5 mags fainter, putting it at mag 15.5 Rather hard visually, but fairly easy for the amatuer observers who usually hunt asteroids, several of whom demonstrably reach mag 19.0. E-mail addresses can be supplied if you want AMSAT to request them to make observations. I would think from memory that the maximum projected area of Ao-40 is more than 1.85 sq meter Dale. Have you the diagrams out of the amsat newsletter to hand? Of course even if its 4 sq m, that only makes it mag 14.8 Tony Beresford (AMSAT Life member 959 ) amomg other things ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
