Ops Shift Log: 05/18/2019, Evening Shift 23:00 – 07:00 (16:00 - 00:00) Time - UTC (PT)

State of H1: Locked at NLN

Intent Bit: Observing

Support: N/A

Incoming Operator: Niko

Shift Summary: IFO has been locked for the past 30 hours, with 12.75 house in Observing. Over all conditions have been favorable for observing. The wind has remained under 20mph for the shift. Primary microseism has come down nicely after the mag 6.8 earthquake in New Caledonia (rode through with SEI_CONF in EARTHQUAKE mode). The secondary microseism has been rising for the past 9 hours, up to 0.1um/s, due to the low pressure system moving in from the Pacific. This system may bring rain and more winds Sunday morning.

   Had the Mid-Columbia Ballet on site to provide gravitational wave inspired dance to the large number of visitors who toured the site.
