TITLE: 06/19 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Oli
SHIFT SUMMARY:

IFO is in DHARD_WFS and LOCKING

Overall a quiet shift with three seemingly different locklosses. Two of these happened less than 2 hours into the lock.

Lockloss 1: During Simulines - Alog 85178. Calibration sweep could not produce the report but BB ran successfully - Alog 85179

Lockloss 2: ETM Glitch - Alog 85182

Lockloss 3: EY Kick right before - Alog 85184

I also reverted the edits that Camilla and Oli made by Camilla’s request. These were to SQZ_FC Beamspot Control, turning it back on (SDFs attached)

Other than that, it seems that locking is taking a very long time to lock DRMI without doing an initial alignment despite excellent flashes. Touching mirrors does not seem to help and whenever DRMI does lock, it stays locked so I do not think this has to do with alignment or too much motion (ground or otherwise).

Microseism is on the rise and there are regular 5.0 quakes happening at the mid-atlantic ridge.
