TITLE: 07/19 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 138Mpc
SHIFT SUMMARY:

- 0:13 - inc 5.0 EQ from Alaska

- Lockloss @ 1:01 - cause unknown

- DRMI locking failed 2x at CHECK MICH FRINGES, so I will try running an initial alignment

• Most of the initial alignment went fine, but I still ran into the issue trying to get SRC to catch, despite having fairly good flashes,  so I am skipping and retrying ISC LOCK
• Relocking was unaided, waited at OMC WHITENING to damp violins

- Acquired NLN/OBSERVING @ 3:45 after accepting an OMC SDF diff leftover from yesterdays OM2 test - Tagging ISC

- 5:27 went into COMMISSIONING due to freezing of ETM cameras (which led to the CAMERA SERVO guardian failing), it fixed, then got stuck a few times before it fixed itself permanently, contacted Dave - scope attached

• It seems that all 3 camera servos, ETMX, ETMY, and BS failed at exactly the same time
• Dave did not see this issue on the IOC, indicating the the problem might be coming further upstream
• We looked at the CDS CA COPY guardian which sends data from the ioc/cameras into the ASC model - I ran a guardctrl log on CDS_CA_COPY during the first failure and saw no evidence of any issue in this guardian node
• The problem unfortunately reconciled itself and we were not able to replicate the problem, this might have to be looked at tomorrow

- Other than the camera hiccup, overall was a quiet night, leaving H1 to Ryan S. going on a 3 hour stretch
