Fri Ops Day Transition
TITLE: 06/07 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Commissioning
OUTGOING OPERATOR: n/a
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 11mph Gusts, 8mph 5min avg
Primary useism: 0.04 μm/s
Secondary useism: 0.17 μm/s
QUICK SUMMARY:
H1's been down for roughly the last 10hrs and recovery/troubleshooting issues with H1 continue with Observatory Mode set to COMMISSIONING. There were dust alarms in the optics lab this morning for a few minutes. Winds are low and microseism has slowly continued a downward trend to the 50th percentile.
Addendum: After quickly chatting with Sheila, the plan is to do single-bounce configuration work this morning (she is getting set-up now).. This is to undo the new OFI (Output Faraday Isolator) spot from yesterday (which had issues due to limits in the OMC suspension). Also trying to recover from Maintenance Day.
