    Last night Lacrosse 5 (05-016A, 28646) "disappeared" 
    (suddenly got about four magnitudes fainter) and then 
    "reappeared" (suddenly brightened about the same).  The 
    times of the sudden magnitude changes were:
    much fainter at about 2:02:21 UTC
    much brighter at about 2:03:39
    This was seen from the BCRC site:  30.315N, 97.866W, 280m.
    Also last night I was able to spot three (faintly) flaring 
    geosats with my 12x60 binoculars.  They were probably not
    brighter than magnitude +8.  It's still a couple of weeks 
    until the real flaring geosat time for our latitude, so 
    these were early to the season.  Also, they were all seen 
    in the area roughly 45 degrees west of shadow entry - two 
    at about RA 21:20, Dec -5 (one at about 3:06 UTC and the
    other at about 3:45 UTC), and the third at about 21:01, -5
    (at about 4:40:50 UTC).  Mike got the second one in the
    scope and found a second one right beside it, separated
    by two seconds or less of time.  I have not yet tried to 
    identify them.  
    I've made some unsuccessful efforts to see Brad's unknown 
    slowly flashing object but am somewhat limited due to my 
    binoculars not being mounted.
    Two nights ago I saw an unknown west-to-east object at
    about +4.5 magnitude ... sigh.
