Ops Day Shift End
TITLE: 10/27 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY: IFO has been locked 28h30. Just finished up a commissioning period from 20:00 to 22:55UTC
LOG:
During commissioning:
- DARM2 Boost turned on 73776
- Calibration updated
- SQZ touched and IR beam centered on FC2 73777
- MICH FF remeasured but no changes made 73773
This morning we had to touch FC2 alignment when the FC unlocked 73770, but since then Naoki has adjusted the FC2 beam centering 73777 so we except this won't be an issue in the future.
