TITLE: 11/22 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Earthquake
INCOMING OPERATOR: Nutsinee
SHIFT SUMMARY:
Earth was still ringing at beginning of shift, but eventually made headway with locking. Transitioned to PEM injections for 2nd half of shift (until a lockloss). It has been 30+min and H1 has shown no issues with ASC (i.e. recycling gain worry Sheila mentioned)...this current lock I did not pause at NOISE_TUNINGS just to see if we could make it without having to wait for any cooling.
LOG:
-
Investigations at Noise Tunings (we had dropped out of lock earlier and Sheila was helping us to stabilize H1).
-
Seismic signals

4:03 PEM Injections starting. Note: Keeping Observaotry Mode in COMMISSIONING state (Robert followed by Anamaria)
-
5:41 GRB Acknowledged. H1 was in Injection Mode, so IGNORING Alarm per L1500117. (Called LLO & Jeremy said L1 was in OBSERVING.)

7:28 NOMINAL LOW NOISE (Wanted to zip right through to NLN & see how REFL WFS faired
