There looks some activity at around MC2 on Wednesday afternoon.
It caused the misalignment of MC2. Misalignment was not found in MC1/3.
It seems that the incident beam on the MC was aligned in the evening.
This increased the MC transmission but it is vibible that the spot on MC2 is shifted from the center.
We need an action on this issue tomorrow in the daytime.
I am working on fixing this. You might some strange stuff going on in the control room screens. Pls ignore it till I am done.
