OPS Eve Shift Summary

TITLE: 12/17 Eve Shift: 0030-0600 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Earthquake
INCOMING OPERATOR: Oli
SHIFT SUMMARY:
LOG:

IFO is in INITIAL_ALIGNMENT and ENVIRONMENT

Still recovering from the 7.4 EQ today in Vanuatu. After this, there were many 5+ Mag aftershocks and our primary microseism is still above the 0.1 line. We briefly left EQ mode for 5 or so minutes before another earthquake (Atlantic Ocean this time) caused us to reactivate.

I began locking at 05:22 UTC and managed to get to PRMI but had no flashes. A few minutes later, another EQ hit and we lost lock. At this point, I started initial alignment. I believe IFO will be able to lock very soon since seismic conditions are coming down quickly.

As the pacific plate shook, Robert took the time to conclude his viewport work, meaning we are capable of transitioning to LASER SAFE once again. I have informed the morning operator independently too.
