TITLE:  Oct 2 EVE Shift 23:00-07:00UTC (04:00-12:00 PDT), all times posted in UTC

STATE Of H1: Aligning/Locking

LOCK DURATION: N/A

SUPPORT: Sheila, Evan

INCOMING OPERATOR: Jim W

Activity log:

00:07 After much ALS alignment tweaking and the wind picking up to around 25mph, Re-locking has been inititated

02:09  Patrick called to let me know that he’ll be in the H2 building for a little while.

02:22 Patrick done in H2 building

04:57 Evan leaving (Patrick still here). There’s nothing more he can do. There seems to be an instability in ALS. Locking doesn’t make it past Switch to QPDs, if it even get’s that far. The majority of the time is spent relocking IMC when it unlocks trying to find IR. Winds are still in the upper 20s.

I placed a call to Sheila to get her thoughts on the situation and Evan suggested that maybe Jim stand down on the OWL shift until the ground motion/wind/ALS is sorted out.

05:10 Called Landry about present condition of IFO and waving off the OWL shift

05:20 Called Sigg about present condition of IFO and waving off the OWL shift. The consensus is Call Jim and let him decide to stand down or come in and confirm proper operation of the Seismic systems, make an aLog and leave.

05:30 Called Jim. He’s going to go ahead and come in NOW and check his stuff and probably NOT stay for the entire OWL shift. His call.

06:10 Jim on site

06:24 Called Landry to give him an update.

Shift Summary: The long and short: No locking for me tonight. Evan, Sheila seemed to be at an impasse and Daniel agreed that this trouble be addressed tomorrow during the day. Wind is still blowing ≥25mph. Ground motion is higher than typical. Not much noise above our raised seismic floor from any earthquakes reported as headed our way. Jim is coming in early to assess the seismic systems and probably won’t stay for the OWL shift.
