                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Jack Dembicky
 I turned on the cooling fans at 19:00 but did not open the louvers due to
interference with DIS cals. Clouds again prevented opening on schedule.
The rain sensor went off (with some sprinkles felt) at 21:10 and around
00:00.
We did open at 02:15 did a quick focus and the clouds quickly came back
but we observed thru them.  A dust event just before twilight (04:45) did
finally force us closed.
Everything ran smooth tonight, while we were observing.
