Both Lowell and the MPC are using current epoch whereas JPL is using those from 2018 Mar 28. The MPC agrees closest with that page. However JPL elements agree with those at Horizons as one would expect - both position and time of close approach and distance. And clearly including perturbations. It will be interesting to see if this rock is re-acquired.
As an experiment I used the elements from https://minorplanetcenter.net/db_search/...d=2018+FE4 (2458600.5). Nowhere close to either of the other sets using gravitational perturbation. I'm watching the news on this rock rather closely. Just for grins. Gives me stuff to do. LOL
