                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J. Dembicky
 I started the cooling fans around 17:10 tonight and had checkout
 completed by 18:00.  Erica logged in around 18:10 and started her lamp
 cals.
 Clouds and the uncertain threat of precipitation prevented us from
 opening.  The Humidity rose around 21:10 to over 80% with continued cloud
 cover.
 It started raining around 02:00 and the 2nd half observers gave up and
 headed back down the mountain around 03:00. It rained for the remainder
 of the night.
