Ops Day Shift Start

TITLE: 06/19 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 148Mpc
OUTGOING OPERATOR: Tony
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 14mph Gusts, 10mph 5min avg
    Primary useism: 0.03 μm/s
    Secondary useism: 0.07 μm/s
QUICK SUMMARY: Locked for 18.5 hours, the range has been decreasing a bit the last hour or two. I'll run some checks to see what's going on.

There is a loud whining in/on the OSB that can be heard from the parking lot and alos in the control room. I think it might be coming from the roof or somewhere in the ceiling. I'll see if I can localize it a bit before calling facilities.

Two updates:

The whining stopped around 740PT and hasn't returned. It went away before I was able to localize it any better than somewhere in the OSB.

I ran Sheila's low range dtt and it looks like our <15Hz is what's hurting us the most at the moment. In particular CHARD Y, DHARD Y, and maybe IMC-WFS_B YAW but the last one is a bit tough to tell.
