    Earlier tonight (August 17 UTC) at about 2:36:27-28 ETS 7
    (25064, 97-074B) did one of the brightest flashes that I 
    have ever seen.  This was at about RA 20:38-39, Dec +17.0
    (2000).  I don't know if I've seen an Iridium flare as 
    bright.  The range was about 405 miles (650 km); Quicksat
    phase angle was 34 (where zero would be full phase and 
    180 new, i.e., backlit).  I was at the Ney Museum site 
    (30.307N, 97.727W, 150m).  Most of the pass was no big 
    deal, but it began brightening after crossing most of the
    sky.  I was wondering if it could have made -10 magnitude.
    It was awesome.
    
    I saw Molniya 3-38 (20646, 90-052A) flashing for the 
    second time recently, to about +6.0 more or less.  This 
    was about 4:20-25, when it was at RA 18:34 to 44, Dec 19
    to 12 (i.e., southbound).
    
    Good old Superbird A has gone on to the west.  I guess 
    it will be back around the beginning of next year.
