TITLE: 05/02 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 151Mpc
INCOMING OPERATOR: Corey
SHIFT SUMMARY: During relocking we were able to catch DRMI without needing to go through PRMI, but had locklosses from ENGAGE_DRMI_ASC and TURN_ON_BS_STAGE2 before I started an initial alignment. During initial alignment we couldn't get past WFS_CENTERING_SRY, so I just took us out of IA and started relocking. LVEA is still in LASER HAZARD.

ASC_AS_C wasn't really seeing much light during the WFS_CENTERING_SRY align attempts?
