    For anyone interested in seeing a flashing geosynch, Gorizont 
    23 has been easy to observe with 10x50 binoculars the last few 
    evenings (in spite of the moonlight and including with some 
    cloud interference a couple of nights!).  Last night it was 
    due south of Texas, and it will be a few degrees farther west 
    tonight.  Its flash period is about 56 seconds.  I'd say that
    the brightest maxima may be +4.5, but they are not all that
    bright; some are down to +6.0 or maybe +6.5.  Last night I 
    observed it twice -- the second while about 80 minutes later 
    than the first.  So right now it's flashing for a long time, 
    making for a pretty good opportunity to see it.  (Sometimes 
    Gorizonts are brighter like this on one apparition but not so 
    on another apparition months later.)  Here's a recent elset:

    Telstar 401 (93-077A, 22927) -- I did manage to catch it three
    evenings in a row, but since it flashes earlier each night, 
    it's now flashing during daylight here.
