    Timed three cycles of Insat 2D at 3:58:54 to 4:03:17 on August 21 UTC.  
    This is a "near" geosynch that's drifting something like 27 degrees to
    the east from night to night (something more than 3 degrees per hour, 
    so it will be south of Europe in just a few days).  The flash period 
    was about 87.7 seconds.  The four flashes were at least +4.5.  Mike 
    McCants observed one flash the following night, quite a while earlier.  
    I failed to find it last night (Aug 23 UTC), possibly because it 
    flashed before dark (?).  Conditions were not good (100% humidity -- 
    for a while fogging up my glasses when I looked through my binoculars!), 
    but I did find Intelsat 512 later along with a number of LEOs.

    Monday night (local, Aug 22 UTC) I observed one flash of Tele-X 
    (89-027A, 19919) without magnification, and it was at least as bright 
    as Altair (about +0.8).  I plan to report some absolute flash times on 
    this one.  I looked for it for a long time last night but didn't find 
    it -- probably rested my neck at the wrong time....
    
    Observing location was 30.3068N, 97.7267W, 150m.
