Ops Day Shift
Transition Summary: 02/04/2016, Day Shift 16:00 – 00:00 (08:00 – 16:00) All times in UTC (PT) State of H1: IFO unlocked. The wind is a light breeze (< 7mph). Seismic and microseism are still as elevated as they were last night. Locking may be somewhat difficult at this time.
We are currently suffering from an unfortunate conjunction of high primary and high secondary microseism, as shown by the ground motion ASDs.
Ground motion ASDs from a gentler, more care-free time (2015-01-09) also attached.
