As posted in k-log 17974, many glithces are observed in ITMX.
To investigate the cause, I added the ITMX signals in the glitch pipeline (Omicron) ~9AM JST and prepared the summary page for them. (see the attached figure)
Although glich shapes are not so similar with each other, I remebered that some amount of air-tech FFUs operation in IYC (beseide KOACHs) caused some glitch noises as klog15127 .
Did you try something ?
