L. Prieto, Carnegie Observatories; A. J. Drake, California Institute of Technology; R. McNaught and G. Garradd, Australian National University; on behalf of a larger collaboration, report the discovery of a supernova in the nearby dwarf galaxy ESO 302-14 (distance about 10 Mpc). The supernova, designated 2008jb, was first found at magnitude V = 13.6 on 2008 Nov. 23, in unfiltered 0.5-m Uppsala Schmidt telescope images from the Siding Spring Survey. Further photometric follow-up observations obtained with the same telescope and the All-Sky Automated Survey (ASAS) 7-cm telescope at Las Campanas Observatory clearly showed the supernova for more than one year after the first detection. The object is located at R.A. = 3h51m44s.66, Decl. = -38o27'00".1 (equinox 2000.0), which is 45".2 east and 12".3 north of its host galaxy. An optical spectrum (range 400-800 nm) obtained on 2011 Jan. 6.1 UT with the 6.5-m Magellan I Baade telescope (+ IMACS) at Las Campanas Observatory shows a broad H-alpha emission line characteristic of type-II supernovae. Details of the discovery, follow-up observations, and analysis will be presented in a paper by Prieto et al. (2011, Ap.J., to be submitted).
