The omicron scans of the top ten Hanford BBH/BNS triggers on December 16th show a notable recurring wave-like glitch. The glitches are present in the following scans: https://ldas-jobs.ligo-wa.caltech.edu/~jacob.broida/Dec16/BBH/GW/1134302174/ https://ldas-jobs.ligo-wa.caltech.edu/~jacob.broida/Dec16/BBH/GW/1134294300/ https://ldas-jobs.ligo-wa.caltech.edu/~jacob.broida/Dec16/BBH/GW/1134291513/ https://ldas-jobs.ligo-wa.caltech.edu/~jacob.broida/Dec16/BNS/GW/1134295111/ Inspection of the auxiliary channels revealed that these signals seem to stem from one channel: H1:ASC-Y_TR_B_PIT_OUT_DQ.The scans for this channel are visible here: https://ldas-jobs.ligo-wa.caltech.edu/~jacob.broida/Dec16/BBH/1134302174/#H1:ASC-Y_TR_B_PIT_OUT_DQ https://ldas-jobs.ligo-wa.caltech.edu/~jacob.broida/Dec16/BBH/1134294300/#H1:ASC-Y_TR_B_PIT_OUT_DQ https://ldas-jobs.ligo-wa.caltech.edu/~jacob.broida/Dec16/BBH/1134291513/#H1:ASC-Y_TR_B_PIT_OUT_DQ https://ldas-jobs.ligo-wa.caltech.edu/~jacob.broida/Dec16/BNS/1134295111/#H1:ASC-Y_TR_B_PIT_OUT_DQ The rest of the scans from December 16th can be accessed from the chart here: https://ldas-jobs.ligo-wa.caltech.edu/~jacob.broida/Dec16/Results.html
