The mystery glitching this team has been thoroughly investigating was present again for ~30 minutes starting at approximately 6 UTC on Dec 13, as seen in this range time series.  HVeto runs over this time period highlight H1:SQZ-FC_LSC_DOF2_OUT_DQ as the most correlated channel (same as in 81587), this time with a significance of 200 (a significance of > 10 is of interest). After checking omega scans of example glitching in the strain data, there is clear glitching present again in this squeezer channel. Similar to previous occurrences of this noise, it promptly appeared and then disappeared.
