TITLE: 10/30 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Earthquake
INCOMING OPERATOR: TJ
SHIFT SUMMARY: Trying to relock after the huge earthquake off the coast of Oregon knocked us down. Currently at PRMI_ASC and TJ is trying to touch up PRMI.
LOG:

14:30 In tail end of an initial alignment
14:33 Initial alignment done, relocking
15:26 NOMINAL_LOW_NOISE
15:26 Observing

15:49 Out of Observing to adjust CARM gain
    - Trying to recreate FSS glitches
15:50 Back into Observing
16:09 Lockloss

16:10 Initial alignment
    - SRC wouldn't lock and SRM tripped twice
16:37 Took us to DOWN and just started relocking
    - Lockloss from LOCKING_ARMS_GREEN
    - Lockloss from ACQUIRE_DRMI_1F
    - IMC took 15 minutes to relock. Relocked after I took it to OFFLINE for a few minutes
17:55 NOMINAL_LOW_NOISE
17:58 Observing

18:00 Out of Observing for PSL makeup air check
18:32 Back to Observing

20:17 Lockloss due to earthquake
    Tripped:
    - ISI HAM{2,3,4,5,7,8}, BS, {E,I}TM{X,Y}
    - SUS PR2, PR3, SR2, SRM, IM4, OFI, TMSY
21:45 Starting initial alignment
    - Could not get XARM IR due to the IMs having drifted during the earthquake. I trended them back with driftmon and adjusted sliders until they were back to where they were before the earthquake.
22:36 Initial alignment finished, relocking
    - Lockloss from PRMI_ASC x2
    - Lockloss from LOCKING_ARMS_GREEN
    - Lockloss from FIND_IR
