              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Mounted DIS at 20:20. Humidity and clouds cleared up just as B-half
program started. Jack logged in for engineering shortly after opening, and
over the night, the ARCSAT dome status reverted from "open" to "closed" on
the weather page, without the dome actually being closed. The humidity was
rising, but the 3.5-m was still open at the time. Jack closed just after
as conditions were worsening. No problems the rest of the night.
***Edit by J.Dembicky - ARCSAT shutter/dome actually closed unexplained by itself.
Since the humidity was rising I did not immediately re-open ARCSAT.
