B and I both showing down on average a little  more than 0.5%, but has a range as deep as \~2%.  Reference stars all normal.   R doesn't have a prior observation using KB23.  Word of caution, this needs to validate and it's all still premature.  You're seeing analysis in real time!   That said, is I band sinking (or even outpacing) B band?  Interesting!!!
