              ------------- ACTIVITY LOG --------------
Observing Specialist:    R.McMillan
We chased holes in the clouds for the first couple of hours of the
night; the observer said he got one successful spectrum.  Then the
clouds got too thick and we closed.
Second half had high humidity and snow, accumulating a couple of
inches.  I ran the snow program andalso the roof heaters.
