Since we rotated ITMX a lot for GRx alignment (klog17407), we realigned the MN OpLevs for ITMX in the morning.
However, the rotational angle is too large and we cannot align the OpLev beam with the current MN OpLev mirror angle, so I rotate the mirror on MN.
After the rotation, the beam comes back to the QPDs and now we can center the TM OpLev and MN OpLev at the same time.

In the afternoon, MN OpLev calibration was done by Yokozawa-san, Kasamatsu-kun, and Chiba-kun.
This report will be hopefully posted by Yokozawa-san later.
