I estimate it was 16.5 mag or slightly > fainter. I think you made a calculation error. It looks like you stacked 4 pictures togeter, right? That's why I see 4 images of the moving satellite. That means the images of all the stars have been brightened by a factor of 4X (or about 2 magnitudes?) versus the moving satellite. That means your satellite is 4 times brighter than you thought or magnitude 14.5 to magnitude 15. Another way to think about it is that stacking the images brightened all the stars except the satellite. In order to brighten the satellite you could have aligned the pictures so the satellite was on top of itself (tracked the satellite instead of the stars) but then you would have 4 sets of each star and they would be dimmer. If you can go back to one of the original 4 images you can make more accurate magnitude estimates. Anyway, good work! - George Roberts mailto: gr@pobox.com http://www.pobox.com/~gr ----------------------------------------------------------------- To unsubscribe from SeeSat-L, send a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@satobs.org List archived at http://www.satobs.org/seesat/seesatindex.html
