The IYV/C temp seemed to be up by 0.1C.
Before starting cryocoolers, we centered MN RPY and V OpLevs.
I turned off 2 of 10 FFUs in the IYC clean booth. 8 are now operated.
The IYV temp keeps gradually increasing.
The IYV temp reached 22.6 and fluctuated.
Because I doubted some troubles of the air conditioner, I asked Hayakawa-kun to check it. However, he could not find any unusual situation in it.
