              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Widespread clouds throughout the night, ranging from medium to thick.  During first half we had nearby radar signals.  Around the middle of the night the clouds thinned a little bit, but never better than borderline.  Also in the middle of the night I discovered a stuck actuator on the tertiary mirror.  I srtuggled with it for a few hours and then decided it was best left for Bill or Ed to work on.  Then the clouds and radar got worse again.
During the downtime, I made a new mask for the echelle slitviewer and worked on DIS spectrograph focus.
