TITLE: 01/02 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
INCOMING OPERATOR: Tony
SHIFT SUMMARY: We lost lock once during the shift from the HAM3 ISI watchdog tripping from the CPS sensor. It then kept tripping the ISI so we're holding in down with the IMC offline and HAM3 in damped until the problem can be addressed in the morning during maintenance.
