I try to avoid using the MP DB's Edit functions. I've messed up the DB too many times in the past 
. Generally the download of the MPC's 'NEAs at Today's Epoch' download button gets all of the NEOs at one time (~30,000 objects).
2023 BU was a special case because it got so close that the osculating elements from MPC never gave an answer for the approach time & distance that matched CNEOS's values. Even the MPC elements for 2023 Jan 27 0000 UT that I just downloaded were slightly in error. The latest elements predicted that it attained 9.7 magnitude! That occurred in twilight & below my horizon.
