              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Wind gusts above closure limits, temps above freezing, and blowing snow kept us closed at the start of the night.
1.6 arc seeing when we finally opened.  Seeing improved to sub arc sec by the end of the night.  I was just focusing the telescope on the fly as needed.
Locked TSPEC slitviewer up, most likely due to a command collision from both myself and the remote observer trying to expose the camera.  Startnubs fixed it quickly.
No telescope problems.
