TITLE: 06/01 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: TJ
SHIFT SUMMARY:
IFO is in DOWN due to PLANNED ENGINEERING (and ENVIRONMENT)
Technically not a shift day since there were no comissioners but Corey and I tried locking for the majority of the day and made it pretty far to where Syracuse Squad and I were yesterday. Serendiptiously however, the environment had other plans. We were hit by 4 6.0+ EQs across that made even green arms impossible. As those were winding down, we had a 3 hour wind event that gave us over 60 mph gusts. We still haven't recovered from the EWs nor the wind which is now sitting between 30mph and 40mph. I guess the good news for the commissioners is even if they did come in today, we would not have had any lock luck!
As for the IFO, we had a successful manual initial alignment, followed by a totally automatic DRMI lock (4 times today since my morning arrival). We would stop at DRMI ASC, touch up PRM and SRM, then move to CARM_5_PICOMETERS and retouch alignment. Then, before FULL_IFO ASC, we would pause and look at the railing ASC error signals. We would touch the relevant optic DoFs (including running the move_ARM_dev.py to adjust any compound signals). In between doing this, we would touch SRM and PRM to maintain a wide POP90 and POP18 (high highs and low lows). Then, we would turn Full IFO ASC on and continue locking. Unfortunately, due to the environment, we were unable to turn full IFO ASC on before losing lock.
ISC_LOCK.STATES is not coming up when I click on "all" on the ISC OVERVIEW. Corey discovered this issue and I can only point to those who last edited ISC_LOCK as a cause of this bug. Will ask the syracuse crew tomorrow.
