The ATLAS (Asteroid Terrestrial-impact Last Alert System) team discovered an 18th
magnitude comet in images taken with the 0.5 m Schmidt at Mauna Loa on 10 June
2022. Although currently classed as a hyperbolic comet by the MPC and JPL, the
uncertainty of measurement suggests that parabolic is more than likely and the
CBET give a parabolic orbit.
