OPS Tuesday day shift summary

TITLE: 11/19 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY: 2ndary microseism has been consistently high (above the 90th percentile) for the whole day and has risen even more in the last few hours of the shift and has reached the top of the plot. It will likely will get even worse tomorrow as the storm off the pacific coast closes in. Wind has been pretty low today. ITMY5/6 is still kind of high.

As of 23:30 UTC we're back to sitting in idle, we unlocked the FSS, ISS, and IMC just leaving the PMC locked.

IFO/Locking:

16:35 UTC While we were down Sheila set the IMC to offline and turned off the ISS first loop off (PMC and FSS locked).
16:53 UTC HAM7 ISI tripped, from a CPS glitch, possibly from the fire crew checking out extinguishers. This is a sensitive area, people walking around can cause CPS glitches.
17:22 UTC LVEA back to LASER SAFE (Transition)
21:23 UTC I started relocking, ALS_X had to be recovered due to the restart. I just trended top mass OSEMs and set the sliders accordingly
21:55 - 22:02 UTC I ran a manual IA to align the SRC as DRMI didn't look good but PRMI did. DRMI looked great afterwords
22:00 UTC Oli swept the LVEA alog81363
22:15 UTC "FAST_SHUTTER test failed", Keita's AS_B FM4 gain filters were still on when they shouldn't have been
23:12 UTC Lockloss at MOVE_SPOTS, lockloss tool. ASC loops were working pretty hard
23:30 UTC ISC_LOCK to IDLE

Some of the maintenance work completed includes:

Glycol piping checks
Fire alarm testing & inspection around site (confirmed PSL encl strobes are working)
CO2Y table loose cables investigated and beam mask adjustment alog81362
New VAC scroll pumps at LVEA and Ends
Replaced bad pressure gauge at PT154 alog81361
EPO pictures and videos of site
ALS beam profiling alog81358
ETMX DAC swap, back to the old DAC alog81350
LVEA oscilloscope installed alog81359
IMC testing alog81356
- IMC offline ISS off, PMC and FSS locked
- Unplugging and plugging in ISS FF cable
- IMC offline, ISS off, FSS off, only PMC

We did not do a DAQ restart
