              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Closed at 21:58 for a little over an hour due to winds. During
observations, I was noticing a large amount of noise in the pmss monitor,
particularly in the second and fourth rows, so I used this time to relax
the primary in the closed dome. That seemed to quiet the noise, and I was
not worried the rest of the night. Secondary behaved well, except for
large differences in "sec des enc" and "sec cmd" readings. This improved
after switching to Agile. Otherwise, no problems.
