              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Clouds and pollen kept us closed for the first part of the night. After
opening at 21:30, I monitored the pollen by checking my car's windshield,
flashlight, and the dome rails. I did not see a lot of accumulation
between 21:30 and midnight, but there was some, so the mirror might be
inspected for cleaning. The press fans only were on during time of highest
accumulation. Tspec unable to recover based on Matt's email suggestions.
No technical problems with TUI. Dcam showed background pattern during
twilight, but not during bright time observing.
