COMET C/2022 A3 (LEMMON-ATLAS)
An apparently asteroidal object discovered on CCD images taken on Mar. 1 UT with a 0.5-m f/2 Schmidt reflector at Mauna Loa, Hawaii, in the course of the "Asteroid Terrestrial-Impact Last Alert System" (ATLAS) search program has been found to show cometary appearance by CCD astrometrists elsewhere after it was posted on the Minor Planet Center's PCCP webpage.
