              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
15MPH wind closure limit due to remaining ice on lightning arrestors.
We could not open due to wind above limits, from Bill, until around 23:30 tonight.  Unfortunately I saw ice on the lightning rods on the enclosure at sunset.
I opened around 23:45 (first program had already given up, no time left for useful data)
When switching to DIS, the Secondary mirror started exhibiting problems moving correctly.  After an hour and a half troubleshooting and a couple of phone calls to Russet and Bill, Russet resolved the problem as the secondary mirror controller needing to be restarted (as well as the secondary mirror needing to be homed, which I had already done previously in an attempt to correct the problem).
I had to close at 02:30 due to winds increasing above 15MPH again.
I re-opened at 05:00 and stayed open the remainder of the night.
I left the telescope at 82 deg alt for APOLLO work during the day.
