TITLE: 12/05 Day Shift: 1530-2300 UTC (0730-1500 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
INCOMING OPERATOR: None
SHIFT SUMMARY: IFO is currently in IDLE. We were eventually able to get the IMC relocked after a lot of touching up optics and the PZT, but it seems like whenever it's been unlocking, it's having more trouble relocking than usual. We ran the dither align scripts for the TMSs and ITMs, and also ran through several full or partial initial alignments trying to get everything looking better. We had issues with basically every part of initial alignment, and after finishing alignment we would still have issues with flashes looking bad, especially for PRMI. Only green arms and MICH have been consistantly looking good.
Matt has started running an inverse filter on the ITMX ring heater over the weekend.
