Ops Day Shift Start
TITLE: 11/01 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Oli
SHIFT SUMMARY: Two lock losses and some commissioning time today. After a long bit of downtime for the IFO, it was recovered this morning, though violin modes were elevated. The lock was not long though and there might be some hints to the reason for the lock loss. Acquisition was straight forward. During commissioning time today we had another lock loss that doesn't appear to be caused by commissioning activities. We are powering up in the relocking process and haven't run into any major issues yet.
LOG:
- 1914 Out of Observing for commissioning
- 2245 Lock loss
