                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Jack Dembicky
 I started cooling fans and opened the louvers at 18:35 tonight.
 Everything went smoothly with checkout and I let the observers use the
 instrument at 20:00. The enclosure was opened at 19:40 to help cooling.
 The seeing was fair at the start of the night at around 1.3 arc sec, and
 varied between 0.9 and 1.9 thru the night.
 The observers spent the first half of the night gathering through put
 measurements with the GFP instrument.  The 2nd half was done gathering
 actual science data. Things seemed to go well for them.
 Everything ran like clockwork tonight with the 3.5m.
