OPS Day Shift Summary
TITLE: 02/26 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Wind
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY:
IFO is in ENVIRONMENT due to high winds (attached screenshot) as well as a 6.1 EQ that just passed.
We are attempting locking since ALS is somehow able to lock and stay locked for over a minute, though DOFs are understandably having a hard time converging. The plan is to finish initial alignment and then go into OBSERVING. Winds are forecast to wind down starting 5PM PST.
