Ed, Patrick

There have been some oscillations occasionally occurring that Patrick noticed on the previous shift and that I have been watching. They aren't destructive to the lock and they wax and wane on their own. Patrick and I also noticed that the "MICH live" DMT trace is "breathing" up from its reference trace between ~3Hz to ~20Hz. I also noticed that the last time these oscillations occurred there was a high SNR glitch in the LF range of the DMT Omega plot.

Excerpt from Activity Log:

07:57 Oscillation: @08:04 IMC-F_OUTMON(tidal) grew to +/- 5 cts. ASC-DHARD_Y & P grew to +/- 2000cts. total duration is ~ 12minutes. Correlating(?) DMT Omega glitch shows up at approx the start time of the oscillation. (08:04UTC + 9 minutes)
