Also if you check the CNEOS website most of these rocks have an H>26 magnitude. Many also have a Minimum Re >0.03 AU. When I calculate their ephemeris they don't get brighter than 19-20 magnitude, if that. Those are hard to spot visually. The website in the Netherlands is a goldmine of information. Since they use the MPC's NEO data file, they also report close approaches of objects that neither CNEOS nor MPC list as having close approaches.
