TITLE: 05/29 Day Shift: 1430-2045 UTC (0730-1345 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY: The morning was spent trying to get back to PREP_ASC_FOR_FULL_IFO as it was found this morning. Locking DRMI was proving to be tricky even though camera flashes looked good and the POP 18&90 flashes also looked good. I would wait 5-10min, make minor adjustments to BS, PRM, or PR2 and try to increase the frequency or magnitude of the flashes. Sometimes this worked, sometimes it wasn't needed, and sometimes we gave up and ran an initial alignment skipping green. We've ran 3 initial alignments so far. We are now sitting at PREP_ASC_FOR_FULL_IFO and control room users are rephasing POP, tuning loops, and checking on other loops. I've had to touch up POP90 &18 at this state with SRM, as long as PRC2 is on to follow. I've also been turning on the RF violin mode damping whenever we sit in this state to help reduce teh high violins that we currently have.
