              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Tspec good.  Took 1500 darks
We were not able to open tonight due to snow and strong winds.
There were problems tonight: The telescope  stopped unexpectedly while executing the snow program. Fritz restarted the TCC but, due to an error I made setting the instrument, the secondary became stuck.  A PR was sent about this issue.
The door to the outside catwalk was blown open at some point in the night but only a small amount of snow was blown in and nothing was damaged.
