=== Agenda ===
- General issue(Yokozawa)
- Yuzu and Jishnu at Kamioka for updating summary pages
- Commissioning report
- Summary of the KAGRA PEM activities at this one month (Yokozawa)
- Brief introduction of the Virgo-KAGRA PEM measurement at May (Yokozawa, Washimi)
- Each member report
- update of reverberation time in KAGRA (Washimi)
- We introduced the now sound injection source, starter (Very nice!)
- The SNR is very good.
- 5% error give by hand
- Fitting the RT60 value
- showed the time dependence of the RT60, the peak frequency was different from Virgo's one
- Measured at both XYend station
- We didn't understand the structure of the spectral
- RT60 is 1s order, that is good result
- Report from Virgo (Federico, Irene)
- Investigation of the Magnetic field injection
- Long term seismometer signal (Irene)
- Future prospect discussion
