This was a very quiet and uneventful shift. Spectrum looked good all night except for a few saturations at EY. The range was a but drifty, going down to the low 70Mpc's at times and then returning for no apparent reason. Spectra of auxiliary DOFs and RF45 stayed right on the reference curves. Omicron recorded 2-4 loud triggers per hour. In last half hour of shift we had elevated seismic due to nearly concurrent smaller earthquakes in Martinique and Alaska. This seemed to excite Dhard a bit but no noticeable effect on the range.
