An 18th magnitude object was discovered in images taken with the 0.5m Schmidt at Mauna Loa on 5 February 2019 by the ATLAS (Asteroid Terrestrial-impact Last Alert System) team. There were pre-discovery images made in mid January from the Heleakala ATLAS. No cometary activity has been detected, however the object is in a long period orbit with perihelion at 6.6 au in May 2020 . It has therefore been given a cometary style asteroidal designation. It may show activity nearer perihelion, though this is only 0.7 au closer than its discovery distance.
