TITLE: 10/23 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY: Currently relocking and at LOWNOISE_COIL_DRIVERS. Still struggling with a 1 Hz oscillation(87658), but we've solved issues with MICH phase margin and with a 0.6 Hz oscillation caused by incorrect estimator settings, so 2/3 of the issues solved?
LOG:
14:30UTC Started relocking
Initial alignment
Lockloss from OMC_WHITENING due to 1 Hz ringup
Multiple locklosses from DRMI and under due to ALSX getting noisy and ALSY having some glitchy drops in power
Locklosses from LOWNOISE_LENGTH_CONTROL, MOVE_SPOTS, etc.
