The perihelion dates in the past appearances are printed on Catalog of Cometary Orbits 1996. The perihelion dates of non-observed returns from 1907 to 1917 are calculated using the Minor Planet & Comet Ephemeris Service. The perihelion date in 1808 is printed on IAUC 4234. The perihelion dates of non-observed returns from 1813 to 1897 are calculated by Kazuo Kinoshita (http://www9.ocn.ne.jp/~comet/pcmtn/0026p.htm).
