                ------------- ACTIVITY LOG --------------
1st Half Observing Specialist: G.Saurage
SPIcam temp was 182.4 at 17:40.
Clear skies, moderate humidity, and a little windy at sunset. Fast
moving patchy clouds moved in about 21:50 making observing pretty much
impossible.  Closed at 23:00 since we had complete overcast and the
satellite images didn't show a break anytime soon. The humidity also
began a gradual climb once the clouds moved in.
2nd Half Observing Specialist: R.McMillan
We closed the cloudcam when it showed a few small droplets.  About
half an hour later, the rain sensor went off.  I set up the
observer's special DIS needs and let him take cals for a while to get
acquainted with the setup.
