30 minutes of no SQZ time this Morning
Austin and I took SQZ_MANAGER from FREQ_DEP_SQZ to SQZ_READY_IFO for 30 minutes of no-squeezing time 16:02UTC to 16:34UTC.
The IFO had been locked for 18 hours. Range dropped from 133MPc down to 113MPc. Both of these range values seem lower than earlier in the week but there was a lot of changes on Friday (69365).

Just checking -- and it seems not a huge difference in squeezing levels over ~10 min with squeezer ASC's ON/OFF. Low frequency differences likely just due to noise technical noise drifts. GPS times:
FDS FC+SQZ ASC OFF (blue): 1367613320 + 10 min
FDS FC+SQZ ASC ON (black) 1367612238 + 15 min
