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.  The comet will reach perihelion at 0.6 au in February 2018 and pass around 0.2 au from Earth in January 2018. The orbit has an Earth MOID of 0.014 au, so an associated meteor shower may be a possibility. The comet could be a telescopic object from December to early February, but becomes poorly placed around the time of perihelion.
