The perihelion dates in the past appearances are printed on Catalog of Cometary Orbits 1996.
The perihelion dates of non-observed returns from 1905 to 1961 are calculated using the Minor Planet & Comet Ephemeris Service.
The perihelion dates of non-observed returns from 1885 to 1898 are calculated by Kazuo Kinoshita (http://www9.ocn.ne.jp/~comet/pcmtn/0009p.htm).
