TITLE: 05/31 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY:  Pretty easy shift with one lockloss due to an earthquake, but relocking was automated besides needing to take the ifo out of initial alignment due to not being able to get past SRC_ALIGN and having SRM M2 and M3 watchdogs trip, and then having to run SRC in manual IA state by state. There were no issue when going state by state.
LOG:

14:30 Detector Observing and Locked for almost 15 hours

16:19 Earthquake mode activated from a couple large earthquakes
16:32 Out of Observing and into Commissioning to try and get more range running SQZ and A2L script 78155
16:45 Lockloss due to earthquake
    - SRM was saturating before the LL
    - Holding in DOWN until earthquakes pass
17:49 Back to CALM
17:50 Started Initial Alignment

18:14 Couldn''t get past SRC_ALIGN
    - SRM M2 M3 watchdogs tripped, I took us out of initial alignment
18:18 Untripped SRM WDs, went to MANUAL_INITIAL_ALIGNMENT
    - Ran SRC alignment states one at a time
    - No issue at all getting through SRC
18:23 Back to DOWN and ready to start relocking

19:09 NOMINAL_LOW_NOISE
19:13 Observing

23:32 Kicked out of Observing by SQZer losing lock  

23:36 Back into Observing
