I got the els from Horizon/JPL and the other info from the MPC search page. I think after the 1st 4 obs, they realized it was near head on (or tail on) so the motion was so small that they waited until the 24 to resume obs. Kind of makes sense, I guess.
So often I've found that max mag does not occur at min dist, mostly due to the phase angle/%. so it behooves me/us to run an ephem for several days each side of close approach.
