                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: Jack Dembicky
 I started the exhaust fans at 16:00 and turned the roof heaters off.
 Louvers were kept closed since we needed to DIS calibrations and required
 a dark enclosure.  The first half observers started taking cals at 17:50
 and I opened the enclosure at 18:15.  Seeing was around 1 arc sec when we
 focused at the start of the night.
 Things ran smoothly for the first half of the night.
 2nd Half Observing Specialist: Russet McMillan
 Second half was clear and apparently photometric, with variable
 seeing that seemed to have a complex positional dependence (0.8-2.5
 arcsec).  Everything worked perfectly.
