              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Frozen ARCSAT at UT 2:26/19:26. Went through full reboot. I could not get
ACP to connect to telescope. Went through reboot again- dome possibly not
slaved. Reconnected ACP.
Humidity readings outside were not reliable, and I found a dewpoint of
-0.5 celcius. I relied on the dewpoint of the new optidew sensor and
compared that to telescope temperatures.
We battled humidity and clouds all night, but they won at 2:40, and we
gave up at 05:15.
