Well, the weather has to be better than the last 6 weeks!! I had 4th magnitude skies a couple of nights ago so was unable to sweep up 2019 Y4 in 7x35 binos. Astorb is still showing last update on 2/27. So no new close approach rocks. JPL and MPCORB seem to be up to date. I've used Horizons (telnet) years ago but now their web interface is easy to use when access to the net is available. Horizons has always been the gold standard since they know the mass of all the solar system bodies to use in the computations. I sent you a private message
