                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Jack Dembicky
 I turned on the cooling fans at 18:00 but did not open the louvers due to
interference with DIS cals. Clouds again prevented opening all night and
humidity also rose over the closure limit around 03:30 and stayed that
way until I closed.
