The perihelion dates in the past appearances are printed on Catalog of Cometary Orbits 1996. The perihelion date in 1953 is calculated using the Minor Planet & Comet Ephemeris Service. The perihelion dates of non-observed returns from 1803 to 1844 are calculated by Kazuo Kinoshita (http://www9.ocn.ne.jp/~comet/pcmtn/0008p.htm).
