Phil, This rock is large but the close pass is ~15LD out so little change in orbit. I get this for b4 and after elements:

I think I ran it back a few weeks ago and the ephem did not vary from that of Horizons with just a simple download from either the MPC or Lowell. Don't recall which. I currently cannot even get this rock into my ST MPDB, no matter what I do. Post in support discussion.
