    Mike McCants and I observed the NOSS 2-2 triplets (91-076C, D, 
    and E; 21799, 21808, 21809) at one-power, about +3.5, for about 
    two minutes, approx. 4:31-33 on July 8 UTC.  Although there was 
    bright moonlight, they were opposite the Moon, and the night 
    was quite clear.  
    
    Follow-up on Orion 3 -- The Thursday evening (early July 7 UTC)
    pass was disappointing.  As it went on towards the east the 
    flashes were brightening, but it was getting farther away and 
    extinction was increasing.  It was ten minutes earlier than the 
    previous night, and apparently the really bright flashes, if 
    there were any, were a few hundred kilometers to our east.  We 
    were compensated some time later with two brilliant Iridium 
    flares (Iridium 16 and 86 "?"), predicted -6 and -9 less than 
    two minutes apart.  They both certainly appeared to be as 
    predicted, and the first one may have been -7.  Friday evening 
    the Orion 3 pass was again 10 minutes earlier than the previous
    night, was thus deep into bright twilight, and occurred as we 
    were in the car on the way to the observing site 
    (30.314N, 97.866W, 280m).
