TITLE: 06/11 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Unknown
INCOMING OPERATOR: Cheryl
SHIFT SUMMARY:
Maintenance Day included recovery from the SUS computer crash earlier this morning. After Maintenance & some initial_alignment pains went for locking. We were running into ASC issues for DRMI and other steps. Sounds like the issue here are that our spots for higher power (37W) don't quite mesh with spots obtained during Initial Alignment. Jenne/Sheila are working on this (as we are in the ENGAGE_ASC_FOR_FULL_IFO state.
