(meteorobs) ETAs May 5/6, 1997 - San Diego



  Hi all,

     Here is a report of my first formal meteorobs seesion for 1997! Boy it's
  great to be observing again..  esp when you get to hang with a couple
  of pros like Bob L and George Z.!!  The ETAs were certainly satisfying,
  though, I kept thinking last night about my previous meteorobs session
  and how awesome a night that was ('96-Geminids!)

    Anyway, for the '97 Eta Aquarids,   Activity was fairly slow at the
  beginning, but my last interval (teff-0.62)  yielded 16 meteors (10 ETA, 6
  SPO).  I observed from 0905-1130 UT and counted a total of 26 meteors.  Took
  a 15min break (see below).  The most notable event..  a wonderful -3 SPO
  that travelled ~40deg.
