    COMMENTS:
    Hopefully USA 186 and 129 are "the Evening Keyholes".. And it's too late for
    me to "ignore message", except I'll not send my response..
    
    Too bright for Lacrosse 4 on a low pass in the West after Sunset.
    
    Yet another New Method was employed. Use what you like, discard the rest,
    especially the obvious error. Never did figure out what was wrong with it..
    
    This is a mix of my "normal" method described at the top of the page and
    wide angle camera on crappy tripod. Waiting on Mailman to bring the Fluid
    Head..
    For 8835, First two points..
    For 28888, First two points..
    For 24680, First point..
    Are "Normal".. 
    
    All other points are wide angle, i.e. 50mm camera lense and a PC164EX2 video
    camera.. Somewhere around 4x6 degrees.. Was none too easy with the sats so
    close together, but things were setup so when the sat passed thru the usual
    setup, I could flip the video selector switch and immediately could follow
    along with the widefield setup. 
    
    Almost missed 28888, as moments before, a sat came the opposite direction
    and I almost aborted filming thinking I had screwed up the direction and the
    "pass" was over. 
    It was 3577..
    
    
    24680 Flared twice..
    5h 2m 12.1s +/- 0.5s to around -2
    5h 4m 27.9s +/- 0.5s to around +0
    Can post small video if anyone wants to see the flares..
