ALL TIMES IN UTC

Arrival:

• 15:00 Taking over from Patrick. IFO is locked at 60Mpc. Why the lower range is unknown to me. Perhaps it is due to work that occurred during the night? Perhaps the ground hasn’t completely settled from the last earthquake?  Wind ≤ 15mph. There has been destructive seismic activity eminating from a volcanic area in the Aleutian chain for the past 8.5 hours. No one else on site, yet. Livingston has been down for the past 8 hours.

Mid-Shift Summary:

• IFO locked. Range is ~60Mpc probably due to HF noise in DARM. According to Kiwamu, this could also be a difference in calibration that we experience from lock to lock. I spoke with WIlliam Parker and Tom Evans at Livingston and they reported their trouble locking https://alog.ligo-la.caltech.edu/aLOG/index.php?callRep=20285. LLO back up at ~17:50UTC. Robert Schofield has been on site since 16:25UTC. Also, at ~17:43UTC I noticed the landscapers clearing tumbleweed and debris in the gravel in front of the LSB. LLO set their Intent Bit at 18:03UTC. Seismic activity has settled back to reasonably nominal levels and the wind speeds remain unobtrusive.
