Shift Activity
TITLE: 12/12 Day Shift: 16:00-00:00 UTC (08:00-04:00 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
INCOMING OPERATOR: Patrick
SHIFT SUMMARY:
IFO locked upon my arrival and an EQ in California caused lockloss. The seismic activity rang down quickly and we were re-locked within the hour. The cause of the next lockloss was undetermined but the CPS on HAM5 was going a bit crazy and was under investigation when I left due to a Hanford Early Release Advisory for the incoming weather because my car is improperly equipped for the amount of snow that we've gotten and is expected today. I'm currently working to solve this issue. Patrick is the evening operator and is on site as are other operators.
