Ops Eve Shift End

TITLE: 12/28 Eve Shift: 0030-0600 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Observing at 161Mpc
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY: Currently Observing and have been Locked for 4 hours. Relocking went well, although we were in OMC_WHITENING for a bit damping violins. I did not have to touch anything besides choosing HIGH_ARM_POWER on the LOCKLOSS_SHUTTER_CHECK guardian (I think that was a side effect of me MANUALing it before correctly INITing it into LOW_ARM_POWER earlier in the locking process - I had reassigned the node manager back to ISC_LOCK but I think it must've already passed the part where ISC_LOCK told it to go to high power) and the evening has been quiet.
