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 date in 1678 is printed on IAUC 5283. The perihelion dates of non-observed returns from 1685 to 1884 are calculated by Kazuo Kinoshita (http://www9.ocn.ne.jp/~comet/pcmtn/0006p.htm).
