              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had snow falling at the start of the night, but it cleared up with no accumulation and we were able to open before midnight.  Skies were eventually  clear, seeing variable.
An hour before scheduled start time, APOLLO had a problem with the GPS clock which may have been due to WSMR jamming.  To give the clock more time to settle after it came back, I let the previous program go long.  We were still able to get some fairly good returns in a short time.
