TITLE: 05/30 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Corey
SHIFT SUMMARY: Moved our SR3, SR2 alignment back to the "+Y" alignment (referencing from alog77694) that we had after the late April optical gain loss and subsequent SR Y movements. On Tuesday (alog78096) they moved to a "+P" position that didn't seem to help us much over the last few days, so today we tried to move to the "-P" location. We got past DRMI but then it looked like there was clipping in the SRC and we eventually lost lock trying to improve the buildups with SR3 movement. We decided to go back to known good place, the "+Y". As soon as we got to low noise and tried to adjust the squeezer, we lost lock when moving ZM4 to its old position. Currently relocking.
