| * BF yaw transfer function showed that it did not move well. It was fount that the position of IP was different from when pumping down started. * IP drifted 2mm in the air, and another 2mm when pump down. (Takahashi) * ETMY IPs were set back to where they were on 1/13. The transfer function now has the similar shape as before, but the Q of lowest peak is a bit low. |
* Searching optimal position of IP of ETMY resulted that the stiffness (DC response level) is the same as what it was measured in the air. Still something at lower stage might be hitting somewhere. * Mirror view by Tcam also moved by 6mm order! It means that the calibration of LVDT can be wrong by factor of 25. * The result of fine tuning showed 1mm off to -x direction. * Vacuum: Kimura * Another leakage was found with 1e-8 order (2 order of magnitude larger than other two). We leave it anyway and we will start cooling. |

| * Alignment and Vibration Isolation: *Izumi * We can move moving masses of BF, or IPs of yaw to check TF can be recovered. * We will play one more day under vacuum. |
* Cooling: Kimura, Suzuki, Yokozawa * We will start cooling around 11AM. |

| * Type A: *Yokozawa * RT model of Type A will be separated into cryopayload and tower. * Type B * SR assembly continues. |
* Alignment: Izumi, Miyakawa * Oplev of ETMY will be monitored at the control room, and misalignment will be restored remotely during the cooling. |

| * Laser hazard: PSL. Green might be used late of the afternoon, then the center area and Y end will be the hazard area. | * WAB cooling test: Akutsu * Temperature monitors are being prepared. * Oplev is ready. * Laser hazard: PSL. Green will be used all the day, then the center up to PR3 will be the hazard area. |

| * Finding causes of ETMY trouble. * Vent might be needed if ETMY is touching somewhere. * Cooling also will be delayed for 2weeks or so. |
