OPS Day Shift Summary

TITLE: 06/12 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Commissioning
INCOMING OPERATOR: Oli
SHIFT SUMMARY:

IFO is LOCKING in ACQUIRE_DRMI_1F

(Started my shift cover at around 10AM PT)

Today we had planned commissioning until 21:00 UTC. We were locked for the majority of it, with much of the commissioning time being spent on SQZ.

We experienced a ETM Glitch Lockloss (not human nor environment caused) - alog 85004. After this, we stopped at PRMI_LOCKED to work on PRMI ASC, but after trying for a while and not making much progress, commissioners decided to continue normal locking.
