Ops Day Shift Summary
TITLE: 10/11 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Commissioning
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY: Lock loss at the immediate start of this day shift, but automated relock. There was some commissioning time starting at 12 PT that also caused a lock loss at 2123UTC. A 6.4M earthquake and a higher microseism have made reacquition a bit slower. I'm currently going through an initial alignment to hopefully help.
LOG:
- 2123 Lock loss
