Robert Noticed Plane Sweep DARM

Probably happens all the time, but while we heard a plane flying by, Robert noticed it sweep on the running DARM spectra here in the Control Room (from the "bucket" down below 60Hz).

This roughly happened from 3:06:30- 3:06:45utc.

Attached are a couple of spectrograms. We will try to predict the effect on DARM from our latest PEM injections.
