              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
GIFS got dinner at 18:00, and ate normally. I began seeing temperature
alarms at 22:00, and re-fed at 22:30. GIFS continued to warm, even after
these two low pressure fills. Temperature alarms were raised again at
~22:30, and I topped it off at 00:30. During this fill, I inspected the
instrument for leaks or condensation but saw no evidence of trouble. I
monitored the temperature closely after that, until it cooled to normal
range by ~ 02:05. No problems with temperature control the rest of the
night.
Weather was clear and calm, producing decent seeing all night. No problems.
