I highly recommend using the latest osculating elements fetched from Horizons. Three days is just simply too far away for this small rock being perturbed as we write. I just reran this with those osculating elements. I'm coming up with closest approach to my yard of 13,190Km at Jan 26, 18:26:22CST.
I get closest approach at 9955 km (center to center) at 00:16:08 UTC on 27 Jan, over 51° 15' S, 116° 28' W (southern Pacific ocean). Moving at 129'/min. Over 2°/minute!
With a phase % of ~11, it might only get to 16th. It will be interesting to keep track of as more precision observations are made.
Right now, I'm seeing 42 obs over 3 days with elements for EPOCH 2459967.5 ! 2023-Jan-23.00 (TDB)
I'm curious where you are seeing magnitude 11.4 and close approach of 28.4k km distance?
Use the osculating elements generated by Horizons
