STATE of H1: Observing at 59Mpc
INCOMING OPERATOR: Cheryl
SHIFT SUMMARY:
LOG:
Survived a pretty good earthquake at 19:30, then lost lock after the ground had calmed down. I looked at the "stock" lockloss plots and it looked suspiciously like Travis' lockloss earlier today. 

While trying to relock, I had problems with OMC locking. The first time I got to DC readout transition, it took 3 tries to get the OMC locked. I waited to check PI, violins etc, and immediately lost lock at DC readout. The second time, it again took 3 tries to get the OMC locked, but I was able to move on.

After getting to NLN, PI mode 27 rang up, but was unresponsive to phase changes. I tweaked the gain down to 5000 (don't know if this helped). Something got touched on mode 19 (not by me) though, and this is what initially dropped LHO out of Observe. I didn't have time to record what was changed, something PLL. Mode 27 eventually calmed down on it's own.
