Day Shift: 15:00-23:00UTC, 8:00-16:00PT, times listed in UTC
Update on IFO:
- morning alignment issues: LSC to ETMX gain was zero when trying to lock the X arm on IR
--- the gain needed to lock was 0.10, when the usual gain set by Guardian is 0.05
- 18:40-18:41UTC switched ISI platforms to Quite_90s from 45mHz
--- reason: Quite_90s are better in wind, and 45mHz are know to be bad in wind, and wind is between 20 and 25mph
--- result: X and Y ALS arm signals dip to 0.7-0.8 while arms are locked in green (max is 1.09)
--- before switching to 45nMz, arms only dip down to 0.9-0.95
- as of 20:40UTC, IFO is well aligned and locking DRMI, but not making it much past DRIM
--- plan is to continue to let the IFO try for DARM_WFS
