OPS Day Shift Summary

TITLE: 11/11 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 152Mpc
INCOMING OPERATOR: Tony
SHIFT SUMMARY:

IFO is in NLN and OBSERVING as of 19:45 UTC (but locked at 19:09). 

Very well behaved IFO today with short reacquisition. Wind is still low and microseism continues to fall.

Had one LL during commissioning (lockloss alog 88043)

OFI temp is stepping once an hour for the next 4ish hours - should not interfere with relocking or anything, Alog 88046.

Additionally, there was a power glitch (not on-site but in town) that flickered lights and caused IY to saturate until power came back a few ms later. Alog 88049.
