  - IFO observed at ~110Mpc with avg of ~73% duty cycle.
  - There was more than usual BNS range variation since Thursday, range would drop to as low as 100Mpc. Sunday was better. alog 51177 
  - We had squeezer problem that resulted in a couple of broadband noises/ range drops / locklosses. alog 51053 alog 51099 alog 51158 alog 51190
  - Hveto round 1 winner was H1:LSC-REFL_A_RF45_Q_ERR_DQ throughout the week, which vetoed most of the low-frequency glitches
  - 48Hz line is clearly visible most days (correlated with ASC-OMC and OMC-ASC channels) alog51080

  - The band in band ratio seems comparatively broader on Tuesday and Thursday for both 4KHz and 100Hz 
  - Elevated microseismic noise thursday through Sunday 
  - PCal X and Y lines seems usual. New deltaL external curve added to the plot. PCal curves had a broader spread on Friday 
  - There was a lockloss on sunday due to power glitch. alog 51197.
