                               ACTIVITY LOG
(* means a trouble report has been issued or appended to)
The telescope was not opened until 3:30 due to high winds, high humidity, and
fog.
Rupali Chandar checked in for her run, but was not able to observe due to the
weather.
Alan Diercks took the time from NM07, but we were not able to begin due to the
fog and high humidity until 3:30.  At this time I encountered a problem with
the eyelid (please see trouble report), and Alan chose to open only the top
half of the mirror covers.  He stated that the seeing was very poor and he
was chasing focus for the entire time he was observing.
