The perihelion dates in the past appearances are printed on Catalog of Cometary Orbits 1996.
The perihelion date in 1901 is calculated using the Minor Planet & Comet Ephemeris Service.
The perihelion date of non-observed return in 1845 is calculated by Kazuo Kinoshita (http://www9.ocn.ne.jp/~comet/pcmtn/0027p.htm).
