    I intended to try to confirm whether or not a bright flashing
    geosynch last Saturday evening was either ASC 1 or Italsat 1.
    I did see a bright flashing geosynch, but it turned out that 
    due to a one-hour mistake in RA (interpolated in my head on 
    site) I was looking in the wrong place -- but saw Telstar 401 
    (93-077A, 22927).  It was at about RA 00:12-00:22, Dec -12.3
    to -12.0 (04:35-45 UTC).  The first two or three flashes were
    very bright (+1 if not brighter).  They were occurring every
    94+ seconds, but as they got fainter I could only see every
    other one (189 seconds).  Two years ago I wrote that it was
    flashing about 15 minutes earlier each night:
    Still don't know about the two other satellites that I had 
    intended to try to see.  I had thought the Saturday evening
    one was ASC 1, but Mike found that Italsat 1 was very very
    near the same position at the same time.
    Intelsat 512 (85-087A, 16101) was not far away from Telstar
    401 earlier tonight, but I didn't see it.  Saturday evening 
    Mike got the telescope on it, and it was tumbling with faint 
    maxima about every 15 seconds.  It can flash very brightly
    if you can get the good luck to see it, and its flash period
    is pretty short (for a flashing geosynch).
    I started to watch Gorizont 23 (91-046A, 21533), but very 
    soon the session was ended by clouds.  Gorizont 23's flash
    period a few nights ago was 63+ seconds.
