CNEOS has updated the close approach for this NEO as 2023-Jan-27 00:29 ± < 00:01 UT at 9.967k km distant. The Condition Code is 3.
Using MPC's elements updated for 2023 Jan 26 0000 UT, ST4v predicts that the close approach will occur on 2023 Jan 27 0151 EST when 2023 BU is 12.7 magnitude, 26.941k km distant moving through Eridanus at 18.6"/sec when it is below the horizon in Columbus, Ohio.
Those trying to view this NEO should use the elements provided by HORIZONS for a time closer to the Minimum Re distance. The osculating elements seem to be changing too fast to provide an accurate position even if only 1 day from the minimum distance. The MPC has elements for the epoch 2023 Jan 27 0000 UT on their website, but I don't know how to get SkyTools to use that data file.
