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 reduced the perihelion distance to 1.1
au in 2019.
