              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Clouds and light radar returns kept us closed for most of A-half. I opened
for science at 00:05, and attempted to get Ming on sky quickly with DIS.
The NA2 rotator failed to rotate, although it checked out in the
afternoon. I restarted the axis motors several times and inspected the
instrument for obstructions. The rotator failed with low-level commands in
talk2boxes. After 15 minutes of trouble-shooting, at 00:20 Ming elected to
give up the rest of her time, as we were not likely to get on sky with DIS
in time for her observations. Switching to echelle allowed CU04 to begin
early, so the time from UV01's program went to her, giving CU04 a total of
5.7 hours of dark time. No problems for the remainder of the night.
