    I observed Gravity Probe B from 08:27:14UT to 08:34:10UT and observed no
    unusual brightness variations.  Appeared to be about magnitude 3.5 at
    closest.  An e-mail from Kevin Fetter suggested this might be an interesting
    one to check out, and after all GP-B is one of the more noteworthy recent
    launches, whether it flares or not.  Also one flyover is not enough to prove
    it doesn't flare.  Astrometry was right on the money.  Temptation presented
    itself in the form of a very nice ISS flyover.
