                  ------------- ACTIVITY LOG --------------
 Observing Specialist: Jack Dembicky
I started cooling the enclosure (fans and louvers) at 15:30.  Louvers were
closed for DIS checkout at 16:40 but fans were left on.  I opened the
louvers around 16:55 when I finished checkout. Opened the enclosure at
17:50.
I finished the Lens program a little bit late (20:06) than hoped, but
still within the switch over time.
The weather center died (no dewpoint or outside temp, actually it got
stuck) around 21:00 tonight.  PR was submitted.  I checked the humidity
with the sling psychrometer and we hit a temp differential of less than 2
deg around 04:50 (MDT) and I thn closed the enclosure.
