Ops Eve Shift Start
TITLE: 06/30 Eve Shift: 2300-0800 UTC (1600-0100 PST), all times posted in UTC
STATE of H1: Lock Acquisition
OUTGOING OPERATOR: TJ
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 7mph Gusts, 4mph 5min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.09 μm/s
QUICK SUMMARY: H1 lost lock about an hour ago but is relocking well; so far up to TRANSITION_FROM_ETMX.
- Wind is low, microseism starting to trend upwards
- All other systems nominal
The RefCav TPD is reading down to 0.69V, showing a warning on DIAG_MAIN, and has been falling over the past couple weeks. Since this is likely due to the increased PMC loss lowering the output of the cavity, I don't suspect fixing the RefCav alignment will get too much out of it, but I can try an alignment this evening if the IFO loses lock.
