==== Weekend ====

==== Report of work ====
 * COM: It was found that calculation of finesse estimation from ring down measurement was wrong. It was actually Xarm ~1450(close to design value), Yarm ~440(1/3 of design value).
 * Type Bp: Satellite box for PR2 was replaced. One new box was no signal at one of the channels. It was replaced to other new one and it worked. 

==== Work plan ====
 * CRY: ITMX cryostat cooler will be stopped.
 * IOO: MZ will be released today from the main path of PSL.
 * DGS: Maintenance work for adding BIO cards.
 * DGS: Camera server maintenance. If you need camera, please use k1cam1.
