As you can see in the attached image, the LVDT signal of the ETMX IP changed significantly, and we found that we could not request ETMX to the ISOLATED state. we found out that the timing of the IP shift was around noon on the 13th, but the workers, Ushiba and Tomaru, did not know what caused the shift. Ushiba and Tomaru said that they released Payload. I don't know what caused the IP shift. At any rate, it was decided to have them check again this afternoon to see if it had been released.
