              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had heavy clouds and even a sprinkling of snow at the beginning of the night.  As the clouds grew thinner the humidity spiked.  But after a little while it improved enough that I was comfortable with opening.  We had poor seeing first half to moderate seeing second half, with waves of high thin clouds once the heavy stuff was gone.
DIS behaved well.  Last night's tertiary problem showed up again on the instrument change to APOLLO, but I was prepared this time and I got it resolved within a few minutes.
