              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
When rotating tert from NA2 to BC1 I got an LMSTOP error. I tried a few moves to other ports with no luck except to NA1. I homed tert rotation and got: "000000436 position error" but move to BC1 failed again. I did NA1 to TR1 to BC1 which worked, and I didn't hear a particularly loud clunk with the successful move (I was up in the dome).
Restarted the dataq netswitch. Omea was frozen all night.
Rainstorms, clouds and humidity all night--no chance to open.
