TITLE: 12/02 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY: Busy day upgrading DAC cards at EY. After suspensions were recovered, we wanted to relock the IFO to ensure the new DACs haven't introduced a problem, so I started an initial alignment. Unsurprisingly, ETMY and TMSY needed quite a bit of adjustment, but otherwise alignment went smoothly. Locking the IFO presented a couple of issues; after DRMI locked, I needed to turn of the SRC1_P loop as it appeared to be pulling alignment away. I turned this off again during ENGAGE_ASC_FOR_FULL_IFO as it appeared to be misbehaving for the second time. Eventually H1 lost lock during MOVE_SPOTS, but we're unsure as of yet what the cause was. H1 is attempting to lock again under the supervision of a few folks still here in the control room.
