Ops Shift Log: 01/18/2017, Evening Shift 00:00 – 08:00 (16:00 - 00:00) Time - UTC (PT)
Shift Summary: Ran initial alignment. Had a bit of problem with Y-Arm green and Input Align. After correcting these, the rest of the alignment went smoothly. The IFO relocked on the first try with no apparent problems. Just after relocking, Sheila pointed out the A2L noise looked bad. DTT confirmed it was. Ran the A2L script. PI Modes 27 & 28 had also rung up. Both were suppressed. Put the IFO back into Observing.
After Lockloss could not get ALS to lock the arms. After several tries decided to run Initial Alignment. The alignment hung up on SRC_ALIGN, which eventually tripped the SUS SRM
WD. I could not reset the M1 watchdog from the OPS terminal. Sheila reset the WD from a remote session, and SRC_ALIGN completed when rerun. Tried relocking again. There was still problems with locking, so ran another initial alignment, which completed without issue.
Tried relocking again but cannot get past SWITCH_TO_QPDS. After finding some O1 aLOGs tried waiting for 3 minutes at CARM_ON_TR for 3 minutes, and for good measure 2 minutes at REDUCE_CARM_OFFSET. This time made it past SWITCH_TO_QPDS and all the way to NOMINAL_LOW_NOISE. Set the intent bit to Observing.
