                              OBSERVING  LOG
   Tonight started out looking like a repeat of the last several nights,
where the wind direction changes to something with an easterly component
shortly after sunset.  However, tonight the wind direction shifted back to
the west after about 22:30.  This made for some of the best images yet on
the 2.5m.
   The entire night was spent on the equator at the meridian.  A good
science run was done on the northern equatorial strip.  At around 01:00 the
seeing was fantastic.  Twelve chips were sub-arcsecond, nine were under .9,
and one was at 0.73 arcseconds!  Seeing was at or below 1.0 arcsecond on
part of the array from around 22:30 until the science run ended at about
02:00.
   Once the run ended about an hour was spent getting the archiving system
back on-line, as something like 5 tape drives had stopped for various
reasons during the run.  Jim Annis managed to keep things going so that the
run didn't have to stop due to full queues.
   As an aside, the Leonid meteor shower provided several nice bright
meteors, but it was more of a drizzle than a shower, at least when I was
outside.
