                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 I started cooling the telescope around 17:00 tonight (Fans only)
 Clouds the whole night with a little break around 04:00 (sucker hole)
 that lasted for about 10 mins before the clouds moved back over (and the
 wind and humidity started to climb near closure limits).  The wind speed
 went over closure limit around 04:30.
