Wednesday evening, 8 Oct UTC.  Location 30.321N, 97.773W, 270 meters.

98-53K/25484 ["Pegasus R/B (2)"], observed in binoculars, was flashing
--  quick, sharp maxima perhaps +4, very faint to invisible between.  
Very rough estimate of period, maybe 20-40 seconds.  Culmination was
2:03:47.

90-78B/20775 ["Cosmos 2098 Rk"], one-power (+3.5?), tumbling slowly.
Very rough estimate of period, maybe 40-60 seconds?  Culmination was
1:49:50.

89-97B/20362 ["Navstr 2-5 Rk" or "GPS 2-05 r1"], seemed to be varying, 
enough that I wrote a "t" by the prediction.  But it may have been a
phase effect, as the pass was WNW to east.  Culmination: 1:35:26.

Tuesday evening, 30 Sept. UTC.  Location 29.400N, 98.660W, 180 meters
(San Antonio, Texas).

92-94A/22286 ["Cosmos 2228"].  Maximum, flash, flash.  Saw at least 
two full periods, one-power then binoculars.  Culmination was 1:20:38.
I noted these (meaningless?) times of three maxima:  1:20:56, 1:21:23, 
1:22:35.  I'm pretty sure this is one that's been known to do two
very bright flashes near culmination on evening passes high in the
east.
