Ops Eve Shift Summary

TITLE: 09/23 Eve Shift, all times posted in UTC
STATE of H1: Corrective Maintenance
INCOMING OPERATOR: None
SHIFT SUMMARY: Commissioners continued making measurements with DRMI locked, but an unstable JAC heating servo causing the JAC to unlock occasionally made this challenging. There will be another log from them posted soon with details, but DRMI is locking fairly easily with good alignment. Leaving ISC_LOCK in 'DOWN' with the IMC locked.
