    Hi George & List :
     Well , long story (see the recent thread Re: Complicated Question about 
    sky geometry) but finally got back out after skies cleared , found the
    nearest group of stars , then back into SatFlare with a much smaller
    search radius and SF spit out only 2 sats (previously mentioned) -
    COSMOS 1651  NORAD  15698 
    COSMOS 1778  NORAD  16961
     You initially suggested C 1651 as the most likely and it certainly does
    appear to be the correct choice . C 1778 was on a very similiar track
    but passed C 1651's position around 11 minutes earlier , which I think
    put it too far away (higher in elevation by 7 degrees) from the sector
    I narrowed it down to .
     Also should mention that Satflare had unknown 060616 (NORAD  90061)
    listed as "Int. Desc. = 06667A" which I believe means it's initial
    description (or similar) was 06667A , so I hope that clears up the
    confusion on that object .
     I should also mention that Heavens Above did not show C 1651 as passing
    over that evening and in fact has no listing of it in it's sat database
    for some reason , unless I'm mistaken , but I tried to find it there and
    had no luck at all .
    Cheers & thanks to you and Bjorn for your help in narrowing this down so
    that an FPAS can be reported for this event .  
    PS : Early morning & Venus/Moon/Jupiter lined up perfectly , and 2
    mornings in row , thanks to the moon rising and drifting on that
    same line between Venus & Jup . Pretty cool & must be fairly rare .
