Hi BMD,
I saw that one, but the show was already over when I caught it. The CNEOS website had a minimum Re of 9.9e-5 AU listed. Real close.
Here's a portion of the ephemeris that I calculated using ST4v (4.0j R12) & the MPC's NEAs at Today's Epoch elements for 2022 Mar 26 0000 UT: [attachment=2300]
The values in the Brief section don't agree because the Brief info was calculated using the elements for 2022 Mar 25 0000 UT.
Now that full moon is past, the number of new MP discovered will increase again. It's typically ~25 objects near full moon & ~2x as many near new moon.
Many of the new finds have H in the 26-30 range, so they're small & rarely get brighter than 17 magnitude even when they get within 0.005 AU or less.
Sometimes we get lucky though.
