PK14U020 = 384P Richard Kowalski discovered an 18th magnitude comet on 25 October 2014 in images taken during the Catalina Sky Survey with the 0.68m Schmidt. Pre-discovery CSS images from 18 October were quickly found and other imagers confirmed the discovery. It is intrinsically very faint, but was discovered during a relatively good return when it was only 0.4 au from Earth; the MOID is 0.2 au. An approach to within 0.5 au of Jupiter in 2017 will reduce the perihelion distance to 1.1 au in 2019.
