              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Much to our surprise, we were able to open at sunset and stay open all
night.  But clouds in the middle portion of the night did hamper observing
for a while and I almost decided to close, until conditions quickly
started to improve.
The ecam filter was definitely not moving properly.  After a round of
diagnosis in the evening we were able to minimize, but not eliminate,
problems for later programs.  It will be worked on during the day.
