OPS Eve Shift Summary

TITLE: 09/25 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Earthquake
INCOMING OPERATOR: Tony
SHIFT SUMMARY:

IFO is in LOCKING in LOCKING_ARMS_GREEN

Very calm shift with a fully auto Lock acquisition from the M6.1 Venezuela EQ this afternoon (alog 87128).

We had one Lockloss due to another earthquake from Venezuela, M6.3. Lockloss alog 87134. I turned on the ASC High Gain before it happened, but we understandably still lost lock.

I've just set IFO to auto-lock, which it will do once the EQ rings down (I expect it to take another 30 mins to get to a lockable state).
