Eve Operator Transition
TITLE: 01/10 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 48Mpc
OUTGOING OPERATOR: No EVE, OWL, DAY operators over the last 24hrs due to heavy snow.
CURRENT ENVIRONMENT:
Wind: 7mph Gusts, 5mph 5min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.30 μm/s
Light snow as I drove onto site (roads were plowed on most of the highways [SR240 & RT10]). On site, snow is plowed for the access road to the LSB/OSB and as well as their parking lots. Snow not plowed down the X & Y arms.
QUICK SUMMARY:
- Sheila took the helm for H1 during the day (see her alogs). Walked in to an H1 in OBSERVING since ~22:00UTC [2PM PST]).
- ~0:15UTC our range dropped from around 60Mpc to below 50Mpc due to snow plowing around CP2 in preparation for LN2 delivery in the morning. This increased seismic in the 3-30Hz bands.
- We are currently running with the OMC LSC Servo Gain of 3.0.
- Talked with Jeremy at LLO (& Anamaria) to let them know we are back to Operator coverage at LHO.
