    The UNID near Superbird A was Intelsat 502 (80-098A, 12089):
    80- 98 A 01-11-08 06:16:44   EC 3134.9 1.0  12 261.2  +4->inv

    I was going to look for the early series of Superbird A, but I 
    was distracted by this one.  I had no predictions for another 
    object that close to Superbird A.  The first flash I saw was at 
    about 3:00:47 UTC.  I lucked out and saw the next flash.  After 
    that I looked at 1/2 and 1/4 period times but only saw flashes 
    every 261.2 seconds.  Some time after Superbird A was done I 
    decided to come here and find some candidates and go back out 
    and try to find it again later.  First I tried a different 
    object but saw no flashes.  With another stroke of luck, I did
    find this one still flashing and watched it a while longer.  
    So the last one I looked for was over three hours after the 
    first one I saw.  All of the maxima were doubles, with a 
    separation of between 0.5 and 1.0 second.
    Earlier I had managed to get to the site in time to see some 
    flashes, from 1:40:37.5 to 1:44:52.8, from Intelsat 512 
    (85-087A, 16101), which is getting low in the west.
