    Wow Ed,
         I was thinking the same thing about the plethora
    of flaring objects of late. I watched the NOSS 2-1
    triplet come out of eclipse high in my NNE at 8 UT
    (3am local time) next to Cygnus. Absolutely
    spectacular. The haze was so bad that I couldn't even
    see the any stars of Cygnus except Deneb. And yet all
    three - as they emerged - were as bright as Deneb. And
    then off to the NNE they went. I believe that they
    were headed almost directly at the sun from my
    perspective, going over the top of the earth. This
    seems to make them flare (and maybe "flare" is a
    misnomer since they stay bright to about 30 deg
    elevation). I've seen this effect for 5 years now -
    late summer night, the triplets emerging straight up,
    off to the NE, brilliant. Will look for Superbird
    tonight (BTW, what's a geosynch sat doing at -12 deg
    Dec. for Austin TX? Is there something wrong with it?)
    Also have a 70 deg in the West - northbound pass of
    Cosmos 1 - can't hurt to look!
