A object of 20th magnitude was discovered on 4 December 2023 in images taken
with the 1.5-m reflector of the Mt Lemmon Survey. It was placed on the NEOCP as
C9YKH92 as a potential NEO. Earlier, PanSTARRS had discovered a comet in
images taken earlier on 4 December, but this was not reported until after the Mt
Lemmon observations were posted.
