              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Afternoon rain and overcast cleared off by sunset, but humidity was high.
I expected that it would remain high given the saturated ground, but
mid-evening the wind shifted from east to south and the humidity dropped.
We were able to open and stay open.  Some waves of clouds passed through
and caused occasional problems with data acquisition, but never enough to
give up on observing.  Seeing was moderate to poor.
During the initial part of the evening while the weather was bad, I made
some progress in investigations of DIS spectrograph focus and SPIcam dark
current.
