Thanks much for posting your OBS. Your comments about glints are distinctly parallel to those made here by other careful observers. Since the predicted time of a glint may not be reliable, I try to record, in addition to the more obvious events, the instants when the brightness is magnitude 5, allowing an observation-based determination of symmetry or asymmetry. See also the discussion in, and referred to in, http://www.satellite.eu.org/seesat/Jul-1998/0367.html > 2. Extra flares prior to the predicted flare may easily be missed. > 3. Extra flares after the predicted flare may also be missed. Thus my suggestion of extended observations of passes in http://www2.satellite.eu.org/seesat/Sep-1998/0013.html Cheers.
