232P/Hill = 1999 XO188 = 2009 W1 Rik Hill discovered an 18th magnitude comet on 18 November 2009 during the Catalina Sky Survey with the 0.68m Schmidt. F. Manca, Bosisio Parini (LC), Italy, suggested that the comet was observed at its previous perihelion passage as 1999 XO188, the observations of which, all by LINEAR, were given on MPS 9249 and 82876. The object was therefore first observed on 12 December 1999. Date 10x10 mag Error Kphot mag Coma ' 28-Dec-18   19.58   0.11 19.1 0.2
