SUPERNOVA 2008jb IN ESO 302-14
     J. 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).
