- Brorsen–Metcalf abstract "Comet Brorsen–Metcalf is a periodic comet with an orbital period of 70 years. It fits the classical definition of a Halley-type comet with (20 years < period < 200 years). It was first discovered by Theodor Brorsen (Altona, Germany) on July 20, 1847, and again by Kaspar Schweizer (Moscow) on August 11, 1847, the prediction was made it would return between 1919 and 1922.On August 21, 1919, the comet was recovered by Reverend Joel Hastings Metcalf (Camp Idlewild, Vermont, USA) as 8th magnitude. Additional discoveries were made by Edward Barnard (Yerkes Observatory, Wisconsin, USA) on August 22, Michel Giacobini (Paris, France), Ostrovlev (Theodosia, Crimea) and Selavanov (Saint Petersburg). By the end of September 1919 it was confirmed as being the same as Brorsen's comet.".
