Ops Shift Log: 01/04/2020, Owl Shift 08:00 – 16:00 (00:00 - 08:00) Time - UTC (PT)

State of H1: Locked at NLN, Range 117.9Mpc

Intent Bit: Observing

Support: N/A

Incoming Operator: Niko

Shift Summary: IFO was observing for the entire shift. Given the winds, this was an accomplishment. Turned off ISI DIFF for a while during the strongest of the winds and gusts. ISI DIFF is back on as the winds have dies down a bit with the coming of the dawn. They are now based in the upper teens with gusts into the mid to upper 20s. As one might expect, the range has been all over, from the 50Mpcs to close to 120Mpcs.

 

The photos are from the Mid-X – perspective toward the End Station and the Corner Station. There is more tumbleweed removal in the near future.
