KAGRA information
Basically, stable operation until 13th early morning. The longest continuous lock was 11h 51m. After recording this longest lock, we found,
1) Y arm GR phase lock fringe became so small. -> temporally we adjust the mid fringe position. The adjustment instruction was already posted by Sugimoto-kun. If possible, we will try.
2) A strange LSC-LOCK guardian code seemed to force the IFO unlock just after Observation mode start. This statement was commented out.
3)MCo coil outputs seem to have large offset. Kokeyama-san will off-load in some timing.
4) In the early morning on 13th April, the ocean became super violent, then IFO cannot be locked. So we gave up the IFO lock and decided to keep only alignment hopefully until the Tuesday morning, or Tuesday midnight in the pessimistic case.
Full alignment maybe from IMMT1/2 for enhancing POP90 will be done in this case.
Anyway, the Monday shift until 9:00 on Tuesday was canceled. I will inform more about our plan later
5) The planed CAL tasks during maintenance will be done after this recovering IFO. 3 or more hours will be allocated.

2)COVI-19 situation in Toyama and SK/KAGRA temporal plan
Toyama Prefecture has also become a pretty dangerous area. I basically recommend you to take"Telework" as a response to it.
But the staff who maintain the KAGRA run should come to Kamioka site. If you come to Kamioka site, please send e-mail to
Situation will change daily, but please deal with it calmly. Thank you for your cooperation.
重力波施設の皆様（神岡）
富山でも感染者が増えつつあります。 今後は、基本的に在宅勤務を推奨します。
ただし、KAGRA観測をリモートで維持するのは困難なので、 KAGRAの観測維持に必要なスタッフは出勤してください。
出勤か在宅勤務かは、私と事務室に報せてください。 あとで就労管理の際にも必要となります。
以上、日々対応が変化しますが、冷静に対処してください。 宜しくお願いします。
