    Getting ready to watch for Iridium 914, with my 10x50s 
    I saw an unexpected flash, maybe about +5 or a little 
    brighter.  Soon there was another; it was moving very 
    slowly -- not the Iridium.  I almost filled up the 
    remaining memory on my stopwatch with flashes every 
    12.9 seconds.  Now Findsat tells me it was most likely 
    Cosmos 1341 (82-016A, 13080).  Almost 15 minutes later, 
    I was getting ready to look for the NOSS 2-1 triangle, 
    and I saw a flash about +5 just above and right of 
    Polaris.  I had stopped my stopwatch on click 100 and 
    had not started the other one, so could only note the 
    times on my wristwatch.  I watched three or four 
    flashes.  It seems that object also was Cosmos 1341!  
    The first flashes were when it was at a range of over 
    11,500 km.  When it went near Polaris, it was close to 
    8,000 km.  Here's a PPAS report on the first obs:
    
    82- 16 A 03-09-07 03:26:45   EC  335.2 0.2  26 12.89  +5.0->inv
    
    NOSS 2-1; the outlier was brightest and was faintly 
    visible without binoculars for some seconds.
    
    I watched GSTAR 1 (85-035A, 15677) from 1:56:49 until
    2:12:09 September 7 UTC.  Phase shift was at about 
    2:05:11.  While I watched it, an entire page of 
    Quicksat predictions went ignored.  But it's just about 
    to flash too early, going into twilight, since it does 
    it about nine minutes earlier each night.
    
    I saw two Raduga 33 (96-010A, 23794) bright flashes, at
    about 5:30:17.0 and 5:30:50.6.
    
    I watched Cosmos 2082 Rk (20625, not currently in the 
    PPAS program list, it seems) for much of its pass --
    
    90- 46 B 03-09-07 02:43:03   EC  298.7 3.0  19 15.7   +4.0->+6.0
    
    Hubble (90-037B, 20580) did some pretty unusual multiple 
    flares.  I wonder what it was doing/pointing at, at about 
    1:50 Sept 7 UTC.  I wonder how many other people saw it.
    
    Observing site was Ney Museum, 30.307N, 97.727W, 150m.
