There seems to be some foolishness going on in the 55-65Hz freq range. Attached are some screenshots of the DARM spectrum to illustrate. I don't see anything corollating to this noise in any of the FOMs. I don't see any visible glitching in the BNS Inspiral graph or the h(t)DMT Omega spectra. Environment is sound, save for some rising microseism. PI mode 27 is riding highand "porpoising" but not high enough to set of a verbal alarm. a2l alignment looks good (i just ran the dither not so long ago). I dunno.
