Ops EVE Shift Start
TITLE: 01/13 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
OUTGOING OPERATOR: Tony
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 17mph Gusts, 11mph 5min avg
Primary useism: 0.06 μm/s
Secondary useism: 0.23 μm/s
QUICK SUMMARY:
Detector is relocking and just got into OMC_WHITENING.
Wind is at a ~constant 20mph. CER temp excursion is almost back to normal range, LVEA temps are starting to settle, but ZONE 1A temps seem to be settling ~1degree higher than before. EX VEA temps are still oscillating a bit.
I've needed to adjust FC1 to get the FC green to lock today, following Wiki: Issues with SQZ FC Guardian. Expect this was due to the LVEA temperature excursion. Accepted new value of FC1 P in sdf.
H1:SQZ-FC_TRANS_C_LF_OUTPUT is now at ~100 where it is usually between 100-130.
