TITLE: 07/05 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY:

Lockloss first thing in the morning.
Got relocked just in time for SuperEvent S250705cb candidate!
Had another Lockloss that pushed the Calibration sweep off until later in the day due to thermalization.

Dropped from Observing for SQZ "Beam diverter is open but no 3MHz on OMC, could be an alignment problem"  Issue @ 20:31 UTC.
When I cleared the History on H1:SUS-ZM6_M1_LOCK_ filters and allowed the SQZ_MAN to do lock everything it seemed to work.
Note: Did not have to move ZM4 or ZM6 sliders to get SQZ_LO_LR back to LOCKED_OMC[20].

Thermalized Calibration measurement @ 21:39 UTC.
