                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Jack Dembicky
I started cooling the enclosure around 19:40, but cloudy skies prevented
opening until 22:10 under cirrus skies.
Seeing was excellent when I checked focus with measurements in the
0.65-0.70 arc sec range in J.
Grim ICC Mac crashed at 22:55, time lost was 6 mins.
We closed at 00:25 due to humidity.  We also had a dust event at around
the same time that lasted until the end of the night.
