* I worked in the measurements of the decay times of SR2. I still have to analyze data. No results to show yet. * Washimi-san reported the feedback signal in SRM F0 was too high. I offloaded onto the fishing rod this morning (klog entry [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=14436|14436]]). According to the [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/VIS/OpsManual/FishingRods|VIS wilki fishing rod page]], this fishing rod does not suffer of any known problems. * I will postpone asking questions about inertial damping again for next week. |

Progress report
General
Type-A
Type-B
- I worked in the measurements of the decay times of SR2. I still have to analyze data. No results to show yet.
Washimi-san reported the feedback signal in SRM F0 was too high. I offloaded onto the fishing rod this morning (klog entry 14436). According to the VIS wilki fishing rod page, this fishing rod does not suffer of any known problems.
- I will postpone asking questions about inertial damping again for next week.
Type-Bp
Type-C
Controls
Electronics
Post O3
- KAGRA is still in the suspended mode. Only remote measurements are available until May 31st (Q-measurement by Fabian, Type-A measurement by Lucia).
- More activities in the control room and the site will be available from June 1st (Noise budget by Ushiba).
- Decision for O3c in Virgo will be done within two weeks (from EO). If O3c was decided, task for O3c will be available as well (e.g. Sensor correction for SRs).
- Post Obs. task has priority higher than task for O3c. Two weeks, at least, in June will be assigned for Post Obs. task.
- The site work towards O4 will be rescheduled.
Post Obs. task (Request), Task for O3c (Plan, Sheet).
