 * Cry and Type A at ETMX: *Takahashi, Ishizaki, Sato, Okutomi, Tomaru, Takahashi, Ushiba, Miyamoto, Enomoto
  * Height was adjusted, and started yaw alignment. GAS filter had a sudden jump, and it is being fixed today.
  * First contact will be removed.
 * BS: *Enomoto
  * DAC had some glitches with no output (even dac kill and master SW are off).
  * It will be investigated more.

 * BRT: Akutsu
  * Alignment was done and BRT worked well, it means that the beam position can be controlled after BRT.
  * Beam shape looks elliptic a bit.
 * ETMX: *Ushiba
 * Confirmed the returned beam at REFL
 * Calibration of OpLev is on going (mostly finished)
 * Start Characterization

* ETMY: *Miyamoto
  * Damping is working well. Less than 2urad RMS.

* BS: *Enomoto
 * Two different problems identified
  * Apparent bi-stability of OpLev -> Replaced the satellite box -> Gone
  * Glitches -> Looks like the same problem as ETMY: DAC output goes to zero

* PCal: Binhua
 * Aligned the beam within the PCal module
 
* ETMX camera: Yokozawa
 * Ready but not installed

* TMS: no one to report

* ETMX: *Ushiba, Miyamoto
  * Start Characterization

* BS: Enomoto
 * Check the glitches over the weekend

* PCal: Binhua
  * Measure PCal transfer functions

* ETMX Camera: Yokozawa
  * Set up necessary components to take high frame rate pictures
