                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J. Dembicky
 I started the cooling fans around 16:00 but did not open due to clouds.
 UW06 & UW07 swapped halves tonight (this log is correct in who was on
 when).  K. Covey was up here tonight training on the 3.5 meter with
 P. McGehee.
 The clouds finally somewhat dispersed around 01:15 when we were able to
 open and get started.  Around 03:50 an orographic cloud appeared overhead
 and stopped observations for about 30 mins.  Clouds came and went all
 night long.
