    Last night we caught Intelsat 512 (16101, 85-087A) before 
    its phase shift, which was at about 4:50:40 to 4:51:00.
    For about 4.5 cycles during the phase shift, I could not
    see it with my 10x50s.  Otherwise, I watched it from 
    4:45:51.40 until 4:58:02.75, plus two more after that 
    using Mike's telescope.  I thought that its brightest 
    maxima were before phase shift and probably were about 
    +4.0 if not brighter.  They're quick like Superbird, and
    the sky conditions weren't great, so I couldn't see any
    without binoculars.  In the telescope, some half-period
    tumbles are visible.
    I envy Kevin's dark sky.  I think it's a pretty rare 
    night when I can see +8 at the BCRC site with my 10x50s
    I had a nice coincidence, that northbound Envisat crossed 
    the same binoculars field of view as southbound USA 160 A 
    and C!
    USA 136 Centaur Rk (97-068B, 25035) is already about to 
    be lost in evening twilight to us here, so it's up to 
    someone east of here to see it later this week.
