The perihelion dates in the past appearances are printed on Catalog of Cometary Orbits 1996. The perihelion dates of non-observed returns from 1903 to 1995 are calculated using the Minor Planet & Comet Ephemeris Service. The perihelion dates of non-observed returns from 1875 to 1897 are calculated by Kazuo Kinoshita (http://www9.ocn.ne.jp/~comet/pcmtn/0011p.htm).
