               ------------- ACTIVITY LOG --------------
 Observing Specialists: J. Davenport, B. Ketzeback
Mostly clear skies at sunset, but high humidity. Were able to stay open
until 23:47 when the humidity climbed and the dew-point difference
dropped. Had to reboot the NICfps icc Windows machine as the camera was
reading out all zeros. Humidity kept us closed second half.
Humidity dropped enough for Apollo, but clouds came in to stay.
