I've been making ephemerides for close pass minor planets using the single MP search feature after getting info online. I tried using the DBPS just now for tomorrow night and came up with a list that does not include rocks from other sources. In particular 2021 RM5 and 2021 RF2. It includes only those below. Even when I broaden the magnitude to put them within reach, they are not included.
All of the 2010 rocks listed are from WISE discoveries with no orbits found, and short 10-14 day arcs. Except for 2010 OT146. Not sure where they even come from in the DBPS as I'm unable to find them in any lists of elements at Lowell, JPL or the MPC even after updating the MPC NEA Today and MPC NEA. Also doing a search for 2010 OG150 at https://minorplanetcenter.net/db_search claims unknown object! I'm just at a loss when using the DBPS. Any guidelines would be helpful.
And why 2003 QQ47, 2011 YQ10 & 1991 TF3 are not listed at https://cneos.jpl.nasa.gov/ca/ nor at https://spaceweather.com/ I can only guess is that the minimum distances are over 30LD.
