                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 We had clouds for most of the night along with erratic winds and
 borderline humidity.  We were able to open for a couple of hours
 during a thin patch in the clouds second half, but when the wind
 and clouds moved in again we had to close.
 The DIS slitviewer needed to be restarted at the beginning of the
 night, but after that everything worked well.
