- Investigation of the TMSX beam shape
- Investigation of the ADC noise
- End X IM 83K
- Y arm commissioning
- Pumping down ongoing
- IY cooling : This week
- Center area commissioning
- Mid-size baffle SRM : Partially done, need to move to final position
- Study for installation of the new laser
- Set inside the PSL room
- Chiller problem
- REFL table investigation
- Check power budget
- Beam dump around IFI
- Many ghost beam

Interesting data
- X arm cavity
- Both IR and GR
- Glitch investigation of the ITMX ADC
- Glitch investigation of the MN oplev light source
- Y arm commissioning
- Both IR and GR
- Center area commissioning
- Main IR
- ALS
- IMC (Input Mode Cleaner)
- ASC (Alignment Sensing and Control) done
- Long term stability check
- Beam power, beam position, oplev monitoring
- Glitch investigation
- Temperature dependence
- Relationship between PSL room
- With PEM channels
- (Hammering test?)
- OMC
- Invesigation will continue after closing the center area
- Because the BS is too fluctuate, it became difficult to investigate
