CNEOS has updated the close approach some more. The close approach is now predicted to occur at 2023-Jan-27 00:26 ± 00:10 UT at 0.00007 AU (9.977k km). The condition code is 5.
Using MPC's elements updated for 2023 Jan 24 0000 UT, ST4v predicts that the close approach will occur on 2023 Jan 27 0035 EST when 2023 BU is 12.4 magnitude, 28.71k km distant moving through Lepus at 28.7"/sec. Here's the Object Info data at ST4v's close approach:
The positions predicted using MPC's osculating elements are changing drastically as the elements are updated each day as the notes in the posted OI illustrate. The perturbations as 2023 BU approaches are really bending the orbit.
BMD, your predictions match CNEOS very well. It will be interesting to see what the predictions look like tomorrow.
