 * CAL: MICH and DRMI calibration model is ready.

 * Remote work should be managed by calling to control room or sending email to gokagra.

 * Smooth transition for when watch dog is engaged has been implemented to Type B. It should be implemented to Type A.
  * When? -> Maybe tomorrow morning during maintenance time or the next week during DRMI.

  * IMC is the first candidate which will be used for run. This is because Guardian is ready for only IMC, not for Michelson or X arm.
  * Needs check the gate valve were really open.
 * Location of spare mirror are not sure. At lease one GTAT mirror exists at Kashiwa campus, but we should have 6 spares.
