[neo_followup] C2KUHZ2 another low-perihelion asteroid on a familiar orbit (virtually identical orbit to 2020 HE)

[Sam Deen]

Hi all,
There's been an absolute deluge of low-perihelion asteroids discovered over the last week or so. The newest one, and probably the most challenging one to follow up, is C2KUHZ2.
The asteroid's nominal perihelion distance is 0.099 +/- 0.025 AU, and it has a longitude of perihelion of roughly 61.6 +/- <4.1, roughly coinciding with 2020 HE and 2019 JZ6 (the linkage I pointed out a few days ago). In fact, the node and arg_peri are virtually identical to 2020 HE!

Currently it's magnitude 21.6 and quickly fading. Observations would be very much appreciated to determine its exact semimajor axis, which is currently very poorly constrained to just ~3 +/- 1 AU.
(ranges are approximated 1 sigma)
             2020 HE      C2KUHZ2q          0.146            0.074-0.124 (0.099)
e          0.942            0.947-0.987 (0.967)
i            20.54           11.3-17.7 (14.5)
peri      216.285       211.6-218.6 (215.1)
node    206.763       206.0-207.2 (206.6)
long     63.048          57.5-65.7 (61.6)
