OPS Saturday day shift summary

TITLE: 12/23 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 152Mpc
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY: Quiet day, I ran a calibration measurement, and we stayed locked the whole shift (35:40). The range has been dropping slightly over the past hour or so, maybe related to vea small temperature changes?

16:35 I went into the warehouse by the VPW to restart the cluster thermostats after the Jonathon called to let me know it was getting warm in there which I had also done last Saturday the 16th.

18:08 I went out to the H2 enclosure and power cycled the 2 in use thermostats and adjusted the fan.

18:00 EQ from Japan, EQ mode at 18:08 UTC, back to CALM 20 minutes later

19:01 I dropped Observing to run the calibration sweep while LLO was relocking following the EQ and went back into Observing at 19:31UTC

20:30 to 21:00UTC I did a quick corner station building walk through, OSB, LSB, mech room, LExC, and staging (I did the H2 encl and VPW in the morning) and saw nothing noteworthy.

H1:PEM-Y_EBAY_RACK2_TEMPERATURE high temperature alert, almost 7 degrees above nominal but its trending down, tagging FMCS, PEM
