TITLE: 08/01 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 146Mpc
SHIFT SUMMARY:
Decently busy maintenance day, Model changes (PCAL, ISIs), DAQ restart, CP1 thermocouple, turbopump test, SQZT0 table work, OMC measurement... Handing off to Corey
Lockloss at 15:16 for the start of maintance activities.
Lock#1:
Yarms power was lower than usual and oscillating a bit but we were still experiencing some shaking from local EQs. During Find_IR it was complaining about Yarm alignment being bad and not searching due to it, I tried to touch up Yarm but it lost lock.
Lock#2:
Yarm went through increase flashes and locked at a normal looking power and had no issues finding DIFF_IR.
We got back into NLN at 21:30UTC and had to wait for; ADS to converge, a potential issue with the new CAL lines to be investigated, and a squeezing issue to be investigated. Back into Observing at 22:02UTC
We dropped out of Observing again at 22:11UTC for a PCAL Y issue that was noticed, back in Observing at 22:16UTC.
