                 ------------- ACTIVITY LOG --------------
 1st half Observing Specialist: Jack Dembicky
 Enclosure fans and louvers turned on/opened at 17:30 tonight to begin
 cooling of the enclosure.  Opened the enclosure at 19:30.
 Instrument was turned over to the observer at 17:47 and we had 1.5 arc
 sec seeing at the start of the night and was between 1.0 and 1.5 most of
 the first half of the night.
 Everything ran smooth tonight.
 2nd half Observing Specialist: Russet McMillan
 Observing went all right second half, aside from a crash of the
 remote observer's Remark due to slitviewer abuse.  Clouds started to
 show up around 0300 and thickened after 0400.  There is a
 dark-current ramp on the slitviewer which I don't recall being so
 strong in previous observations, but it wasn't an impediment to
 tonight's observing.
