If you're referring to the list of 100 or so Brightest on Celestrak, I set that up to include satellites that are usually easy to see for the average observer. I set a mag limit of about 3.8 for that. This is determined by actual observation. I think other lists use theoretical predictions based on assumed size. I don't know what their limits are. -- Jay Respler -- JRespler_at_superlink.net Freehold, New Jersey _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Thu Mar 27 2014 - 22:40:36 UTC
