Aren (Ari) Heinze discovered an 18th magnitude comet in images taken with the
ATLAS (Asteroid Terrestrial-impact Last Alert System) 0.5m Schmidt at Mauna Loa,
Hawaii on 28 September 2017. It had been posted on the PCCP as A104nX1. The
comet passed around 0.2 au from Earth in January 2018. It has an Earth MOID of
0.014 au, so an associated meteor shower may be a possibility.
