- (Yuzurihara) read BLRMS data and made the several plots with 1% and 99% percentile.
- When KAGRA will be locked as observation mode?
- hopefully after july, there will be lock trial for two monthes(?)
- When you set the 1% criteria, always you throw away the 1% data?
- We might need to consider the better procedure to care that point.

- Next step is coincidence search with signals around ETMY including local control sensors.
- ITMX glitches
- K1:VIS-ITMX_F3_LVDTINF_GAS_{IN1,OUT} have glitches.
- It seems to occur around AA chassis. (AA and cable replacement didn't help to improve situation).
- We will try to find glitches on other channels on the same ADC board.
This channel should be added to Omicron search on SummaryPages.
- DQR progress
- DQ flags for O4
- No updates
- O3GK paper
- Threshold used for computing a glitch rate was changed as SNR=6.5.
- It's a same criterion with LIGO, and Virgo.
- Both GEO and KAGRA's results are now computed and draft was also updated.
- 120Hz glitches
