Title: Owl Shift Transition Alog, Owl Shift 07:00-15:00UTC (00:00-08:00PT)
H1 State: Has relocked and made it to Low Noise and Observe, but only lasted 2-3 minutes - Relocked and back in Observe
Outgoing Operator: Corey
Help from: Sheila, Kiwamu
Details:
For the first lock, my interventions:
- I tweaked TMSY to raise the ALS arm power from 0.8 to 1.01
- I tweaked BS to lock DRMI, and then again after DRMI locked in order to get WFS to engage
- IFO went to Low Noise after that without issue
07:34:04UTC - IFO in Observe
07:37:06UTC - lock loss
For the second lock, my interventions:
- I tweaked BS after DRMI locked before WFS engaged
- IFO went to Low Noise after that without issue
08:06:14UTC - IFO in Observe
Issues?
08:07:53UTC - ETMY saturation
08:16UTC - Currently: IFO in Observe and range is 75Mpc
