              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky, A.Shugart
Jack began the night for me with clear skies and no problems. The wind
picked up at ~ 22:30, and soon forced us to close. We attempted to open
again at 01:10, but the axis motors would not initialize. It took an 1.5
hours of troubleshooting, at least half of which we would have been closed
for wind anyhow. I split this difference, and we got on sky again at
02:40.
No problems after that.
