  * Michelson lock lasted longer than 2 and half hours!
  * Alignment control from IFO to ETMX was implemented by dithering ETMX.
  * PR3 alignment was implemented by baffle signal.
  * ETMX damping might be a cause of lock lost.
  * ETMY yaw damping inclease pitch motion by coupling. It will be improved today.(Ushiba)
  * BS oplev is fed back to not only TM but also IM. (Arai)
  * OLG was measured in the daytime.
   * Error of TF of actuator is ~20%.
   * 120usec delay exists in the MICH loop.
  * BS oplev sensitivity was improved by increasing whitening gain.
  * Longest lock of the last night was ~8hour.
   * Baffle PD signal is used to BS alignment.

 * WAB: *Akutsu
  * Heat consumption is estimated well. 10ppm produce 4W and it will be absorbed by WAB and now it is simulated by heater.
  * Equilibrium temperature was 21K.
  * Damping became to strong in low temperature.
 * 40Hz periodic noise was seen every 16min. It is air compressor.
  * It can be stopped during operation.
  * Timing to IY0 will be connected today.

  * Line injection is being tested.
  * UGF serve will not be implemented, so change of optical gain is compensated in off line.
