TITLE: 11/08 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 161Mpc
INCOMING OPERATOR: Tony
SHIFT SUMMARY: Putting my alog in early since I'm leaving early. Currently observing at 160Mpc and have been Locked for 50 minutes. Secondary useism is high-ish, but we just went back to CALM from USEISM. The relock attempt from when I came in this morning wasn't too bad, and then relocking after the lockloss was also not bad besides SRM tripping during SRC align in IA and not wanting to lock SRC.
LOG:

15:30 In PREP_FOR_LOCKING
    - stuck?
15:42 DOWN and then started relocking
    16:28 Lockloss from MAX_POWER
    16:43 Lockloss from ACQUIRE_DRMI_1F
    16:45 Started an initial alignment
    17:04 Initial alignment done
17:55 NOMINAL_LOW_NOISE
17:59 Observing

20:17 Lockloss due to earthquake
    20:25 Started an initial alignment
        - SRM WD tripped during SRC aligning
            - I raised the WD trip level for SRM M3 to 200 from 150 since we get this tripping quite a bit
            - Tried SR2 align and AS centering again, didn''t work
            - Left IA
    20:56 Left IA, relocking
