TITLE: 05/22 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
SHIFT SUMMARY:

Locking:

• DRMI was struggling to lock this morning; two attempts where SRC1 wasn't converging and we couldn't hold it
• 15:50 - Opting for a SRC alignment to see if that helps
• 16:21 - Manually aligned SRM as Automated SRC align wasn't doing well enough; now trying DRMI locking again
• 17:00 - DRMI ASC still wasn't working; hand aligned PRM and SRM to maximize POP18 and minimize POP90
• 17:21 - DRMI ASC worked, moving up
• 17:57 - Nominal Low Noise
• 18:23 - Observing
• 19:04 - Dropped Observing for 26 seconds from H1:CAL-INJ_CW_GAIN going to 0, then back to 1 just 10 seconds later
• 20:27 - Lockloss from PI mode 29 ringup
• 21:00 - TJ and I notice that PR3 drifts during lock and slowly moves back at lockloss. TJ moved PR3 slightly to improve ALS flashes
• 21:41 - High wind has made locking challenging
• 22:20 - Running initial alignment to test some automation; might as well since winds are too high to lock
