              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Partly cloudy skies and moderate seeing.  The dome was open all night,
but there were some periods during first half when the clouds were too
thick to take any data.  DIS blue was still down tonight, but the problem
preventing us from running the red half only was resolved.  Accordingly
the scheduled first half program ceded time to another CU program which
could make use of the red side of DIS; the second half program was
already more reliant on the red so no change was needed there.
