There are many glitches making up the “fuzzy” range time from 07:00UTC 23rd November 2023. We identified glitches using ndscope of the DARM BLRMs, (plot attached showing yellow, green, blue BLRMs getting worse at t-cursor) and then used ldvw.ligo.caltech.edu Q-transform to plot omega scans of the glitches. Original troubleshooting in alog 74377. 

Attached is a pdf containing the glitches seen between 07:00UTC and the lockloss at 10:10UTC. There are many more glitches than usual and lots of different types of glitches.
