Metcalf in 1906 but subsequently lost. A new observation in 1991 by Howard J. Brewington was matched to the 1906 sighting; the orbit was computed and the comet was observed again on its returns to perihelion in 2001 and 2011.[2] References1. ^{{mpc|97p}} {{Comets}}{{PeriodicComets Navigator|96P/Machholz|98P/Takamizawa}}{{DEFAULTSORT:Metcalf-Brewington, 097P}}{{Comet-stub}}2. ^{{cite web |url=http://www.aerith.net/comet/catalog/0097P/index.html |title=97P/Metcalf-Brewington |first= Seiichi |last=Yoshida |work=Aerith Comet Catalog |date=2012-06-24 |accessdate=2016-03-29 }} 4 : Periodic comets|Discoveries by Joel Metcalf|Comets in 2011|Astronomical objects discovered in 1906 |
