    This is especially for western USA flashing-geosynch observers --
    Last Monday evening (June 6 UTC) I saw two apparently stationary 
    flashing objects in the field of view of my 10x50 binoculars and
    watched them for five or six minutes -- but then lost them both
    when I picked up my Bright Star Atlas in order to try to figure
    out where they were.  Duh!
    Upon further checking, it appears conceivable that the fainter one 
    with a period of 8+ seconds might have been Hipparcos.  If so, then 
    the other, much brighter one (at least +4 if not +3) with a period 
    of 39+ seconds might have been Intelsat 512 (16101, 85-87A).  That 
    satellite is still in pretty good position for observers in the 
    western USA for a few more days at least, if anyone wants to try to 
    confirm if it is or is not flashing or tumbling every 39+ seconds.
