    Flashes from two observed without binoculars:
    93-077A, 22927, Telstar 401 -- 6 flashes, about 134 
    seconds apart, +1 max (easy to understand how the 
    people in the hot-tub in Houston were able to see it), 
    from about 2:33:32.2 to 2:54:40.9.
    89-041A, 20040, Superbird A -- 4 flashes, about 22.6 
    seconds, +3 max, after phase shift, I think, from 
    about 3:27:43.6 to 3:28:51.3.
    Probably a few of this next one's flashes would have 
    been visible without binoculars:
    90-077A, 20771, BS/Yuri 3A -- very peculiar flash 
    pattern, my times for a few bright ones were from 
    about 4:26:13.5 until 4:36:36.7.
    In binoculars I saw one very bright flash not far from 
    Superbird A.  It may have been Intelsat 510 (85-025A, 
    15629), which has been out of service for about three 
    years.  Mike watched the spot through his 12x80 finder
    scope (3-degree FOV) for several minutes but saw only 
    Superbird A flashes.
    Gorizont 14 (87-040A, 17969) was again easy with 
    MOS 1-A (87-018A, 17527) made a spectacular flashing pass.
    NOAA 14 (94-089A, 23455) flared three times.
    NOAA 6 (11416) PPAS report, maxima not sharp:
    79- 57 A 02-11-25 01:40:47   EC  147.5 4.0   6 25  
    FUSE (99-035A, 25791) was fairly easy to see without 
    ISS and Space Shuttle, pretty bright for as low as 
    they were in the south; I got that they were a little 
    over five minutes apart.  They both went pretty near 
    alpha and beta Grus.
    Observing site was BCRC: 30.315N, 97.866W, 280m.
    Weather/cloud models don't look very promising for the 
    next few evenings.
