Comet 213P/ Van Ness is a recently discovered periodic comet that can reach 13 magnitude at a favourable return. It is another member of Jupiter's "family" of comets and has a perihelion distance of about 2 AU. The 2011 return was fairly favourable and the comet peaked in brightness at around 14th magnitude and displayed a fairly long straight tail.
