The perihelion dates in the past appearances are printed on Catalog of Cometary Orbits 1996.
The perihelion dates of non-observed returns from 1904 to 1957 are calculated using the Minor Planet & Comet Ephemeris Service.
The perihelion dates of non-observed returns from 1825 to 1880 are calculated by Kazuo Kinoshita (http://www9.ocn.ne.jp/~comet/pcmtn/0007p.htm).
