So the real flash period of 95-058B is more likely 1 sec instead of .5 sec. Do you or anybody have an idea why this secondary maximum is varying in intensity from day to day? I've also observed this behavior with 94-074B (Resurs 1-3 r). I suppose it's linked to the satellite-observer geometry, but I can't really figure out why. Clement Drolet 76266.2530@compuserve.com
