                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Another stormy night filled with rain and fog. At the beginning of the night
 we had several ground fault failure alarms from the new fire alarm system.
 Around midnight the dewpoint sensor flat lined. We were clearly in closure
 conditions (heavy fog).
 I used the cloudy night to work on "not so" FastcamOne, for Jon Davis, and
 FastcamTwo data reductions.
