    Last night, at a star party at a dark site, we did not see 
    GPS 2-21 PKM (22702, 93-42C).  
    
    On the other hand, before getting started I was looking at 
    Orion and happened to see a flash in the vicinity.  I was 
    pointing the location out to Mike McCants when it flashed 
    again -- about +2, still before astronomical twilight.  
    The first one I recorded was at about 1:12:48.5 Feb 6 UTC.  
    These bright flashes did not last very long -- faded to 
    +10 (visible only in Mike's telescope) in less than 20 
    minutes.  I thought I had predictions for a known geosynch 
    flasher in that location in the sky, and Mike found that 
    TDF 1 (19621, 88-98A) was a good match.  Either the period 
    or the half-period was about 16.5 seconds.
    
    Then there was a pass of Hubble Space Telescope.  At first
    it wasn't much to look at, but after passing due south it
    began to brighten and kept brightening more and more until
    it peaked at -5 at least, at about 1:30:18.50, plus or 
    minus about one second.  This was an incredibly spectacular 
    HST maximum, and many of the amateur astronomers at the 
    site for the star party saw it.  
    
    At this dark site, some flashes that Gorizont 17 (19765, 
    89-4A) displayed were visible at one power.  
    
    At 4:10 UTC there was a great meteor, about -2 or -3; it
    went straight south between Orion and Canis Major, was 
    somewhat orange and shed some sparks.  It had a long train 
    and was moving pretty fast.
    
    We could not have asked for a better night, except possibly 
    for it to be a bit warmer!
    
    The location is about 30.884N, 98.430W, about 360m.
