TITLE: 07/11 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Oli
SHIFT SUMMARY: We had a large and close 6.5M earthquake off the coast of Vancouver Island stop us from observing for most of the shift. This earthquake tripped all of the ISIs, but the only suspensions that tripped were IM1, SR3, SRM. Getting back was fully auto(!), expect for untripping WDs and some stops to allow for SEI testing. The delayed commissoining was then coordinated with LLO to start at 2030 UTC (130pm PT). A lock loss happened 1.5 hours into commissioning, the cause seeming to be one of those ETMX wiggles again. Relocking now has been full auto with an initial alignment so far.
