304P/Ory = 2008 Q2 = 2014 L4 An 18th magnitude apparently asteroidal object discovered by Michel Ory of Delemont, Switzerland, on CCD images obtained with a 0.61-m f/3.9 reflector at Vicques was found to show cometary characteristics after posting on the NEOCP. The comet passed 0.3 au from Jupiter in November 2005, before which the perihelion distance was a little larger. 2008 Q2 was recovered by Hidetaka Sato in images taken with the iTelescope 0.51m astrograph at Siding Spring on 2 June 2014.
