                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st shift: Russet McMillan
   We opened a little late because difficulties calibrating the
high-resolution gratings delayed the observer's calibration images. Once
we were open, the seeing was good, the skies were mostly clear, the
pointing (after correction) was fine, and the tracking (with the guider
running) was perfect.
 Observing Specialist, 2nd shift: Noel Camron Hastings
   Second half started with a refocus and all seemed to be operating
well. We did have some slit imager failures at one point, about 3 and
then they stopped. Telescope had trouble tracking on last object when we
were near zenith (87+ degrees).
