Ops Day Shift Summary
TITLE: 11/03 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Unknown
INCOMING OPERATOR: Ed
SHIFT SUMMARY: IFO is at NLN. Robert and Matt are taking measurements at end X. The SEI config at end X and end Y are on BLEND_Quite_250_SC_useism. Robert will call when he goes to end Y to have us turn off the optical lever damping there.
LOG:

16:07 UTC Robert to LVEA to setup for tests. May increase PSL makeup air, but not enough to keep from locking.
16:38 UTC Trouble keeping PRMI locked. Starting initial alignment.
? Robert back
16:51 UTC Betsy and Jason to mid stations
17:09 UTC Initial alignment done
17:10 UTC Peter to optics lab
17:18 UTC DRMI_LOCKED. Diffracted power is low (~.6). Adjusted reference signal to bring it back to ~4.
17:54 UTC Error message: 'POPA has a large offset. ENGAGE PRC1 by hand.' Stefan looked and said the offsets are not really large so he manually reran ENGAGE_ASC_PART2. The error message went away.
18:15 UTC Stopped at REDUCE_45_MODULATION_DEPTH. Diag messages saying waiting for soft loops to converge. H1:ASC-AS90_OVER_POP90_MON is oscillating wildly.
Stefan says the limits on the check to move on are not large enough, and it is safe to do so.
18:37 UTC NLN
18:45 UTC Stefan moving spot on PRM
19:05 UTC Lockloss (Stefan?). Diffracted power came up to ~7.
19:23 UTC Lockloss from ANALOG_CARM
19:48 UTC NLN
19:59 UTC Running a2l
cd /opt/rtcds/userapps/release/isc/common/scripts/decoup
./a2l_min_LHO.py

20:06 UTC Karen cleaning in H2 electronics room

./a2l_min_PR2.py
./a2l_min_PR3.py

~20:27 UTC Restarted lock clock. One of the two python scripts had crashed after losing connection to H1:GRD-ISC_LOCK_STATE_N.
20:39 UTC The trace for LLO on the DMT range plot just disappeared.
20:54 UTC Richard to CER mezzanine to look at some grounds
21:01 UTC Kyle to mid X
21:11 UTC Joe moving forklift a few feet from OSB wall
? Richard back
21:34 UTC Noises in control room from cleaning on roof.
21:58 UTC Cleaning on roof done.
22:00 UTC Kyle back from mid X
22:03 - 22:10 SEI at end X and end Y changed to BLEND_Quite_250_SC_useism
22:12 UTC Robert to end X
22:18 UTC Jim W. restarted SEI ETMY guardian node
