                              ACTIVITY LOG
Bias frames were obtained with SPIcam for UW09.  Ripples were evident in
those frames.*  Opened the dome at 17:55.  Sky flats were obtained for
UW09.  The Altitude and Rotator axes failed to reach desired locations
during a slew.  Did a slew through a large altitude change then everything
worked fine.   The Altitude failed during a slew later in the night.  Once
again a huge altitude changing slew fixed the problem.  Had intermittent
clouds throughout first half, but they were thin enough to still image
through.  Closed at 00:25 just after switching to DIS when the clouds
thickened considerably.  Some calibration spectra were obtained by WS02
during the closure.  Stayed closed remainder of night.
