Ops Owl Shift Summary
TITLE: 01/22 Owl Shift: 08:00-16:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Ed
SHIFT SUMMARY: Ran an initial alignment after the lock loss from the earthquake and made it back to observing. Lost lock for an unknown reason and have struggled to relock since. I have resisted doing another initial alignment, but it may be necessary.
LOG:

Cheryl took ISI_CONFIG to WINDY_NO_BRSX because it appeared that BRSX was starting to ring up.

08:45 UTC BRSX appears to be stable. Took ISI_CONFIG to WINDY.
08:48 UTC Starting attempt to lock arms on green.
09:30 UTC Locked on arms green. Needed to move TMSX a significant amount in yaw.
09:35 UTC Starting initial alignment.
10:03 UTC Going to PRM_ALIGN unlocked the IMC. FSS is oscillating. Turning the FSS autolock off and back on fixed it.
