TITLE: 07/11 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Earthquake
INCOMING OPERATOR: Ed
SHIFT SUMMARY: 6.6M earthaquake at the start of my shift left us waiting for a few hours, then some trouble keeping the mode cleaner locked after initial alignment, followed by ETMX violin mode 507.194hz ringing up. With +60 phase and +0.25 gain it seems to be stable(ish) at an RMS of 7. The OMC trans camera has a lot of movement, it seems to really be struggling, and the OMC_LOCK Guardian will not get to READY_FOR_HANDOFF presumably from this high violin mode.
