With Satoru Ikeda

We checked the beam position at Tx module trapezoid area, then could not find any unexpected beam out from the Tx module.
So the glowing area in the upper left on the Y image should be caused by the main Pcal beam, which can be the refracted beam by the ETMY.

Also, we checked Pcal area at both Xend and Yend to see if there are any damage caused the earthquake, but no issues were found.
