TITLE: 03/27 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing
INCOMING OPERATOR: None
SHIFT SUMMARY: Just started observing. Had a lockloss a couple of hours into my shift and then a couple earthquakes that kept us from locking for a while. After that, I was having issues with DRMI and PRMI and couldn't get them to catch by adjusting by hand, so I reverted the OPTICALIGN offset changes that Jennie had made earlier with the beam walking. That actually ended up making the alignment worse, and I had a lot of issues trying to revert those optics to different times, and then reverting all optics (except sqz) to multiple different times, before being able to get past DRMI/PRMI after an initial alignment.
This means that the first offset script(76732) didn't get to run at 10pm either. :(
Attached is the one SDF I had to accept to get into Observing.
LOG:
2300UTC Detector locked for 2 hours, commissioning going on
** This was due to Nutsinee and Naoki''s diode centering at HAM8 **
2316 ZM3 started was constantly saturated
2319 Saturating stopped
0050 Lockloss
0121 Started MANUAL_INITAL_ALIGNMENT
0153 Earthquake mode activated due to incoming earthquake from Fiji
0156 INITIAL_ALIGNMENT complete, relocking
0206 Lockloss from ACQUIRE_DRMI_1F
0210 Lockloss from FIND_IR (due to earthquake), sitting in DOWN while earthquake passess
0319 Starting to relock
0323 Earthquake mode activated due to a nearby earthquake off the coast of Oregon
0325 Lockloss at FIND_IR due to nearby earthquake, holding in DOWN
0341 Starting to relock again
0357 Earthquake mode activated due to Alaska earthquake
0416 Cycling through CHECK_MICH_FRINGES, so I went to DOWN and ran MANUAL_INITAL_ALIGNMENT only for PRC, MICH, and SRC
0431 INITIAL_ALIGNMENT done, starting relocking
0451 Lockloss after cycling through PRMI/DRMI
0524 Reverted all optic offsets (except SQZ) to 03/26/24 21:16UTC (beginning of the lock before maintanence)
0544 Reverted all optic offsets (except SQZ) to 03/26/24 06:50UTC (beginning of last lock)
0527 Started INITIAL_ALIGNMENT
0621 Started relocking

Just as an FYI - This SDF diff is from the picomotor driver at the end station. I'm not sure why there's a diff to begin with, but the driver is off so it doesn't matter much what position the channel was left in.
