                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Smooth sailing tonight.  Seeing was pretty decent all night.
 NICFPS ion  pump was pegged at the start of the night.  I assume the
 NICFPS folks knew aboout this, since they were onsite, but I never saw
 them to tell explicitly.  I sent an e-mail to Nick/Mark this moring.  The
 pressures readings (vacuum) on NICFPS seem to be OK.
