SUPERNOVA 2010jj IN NGC 812
     J. M. Silverman and A. V. Filippenko, University of California, Berkeley;
and R. J. Foley, Harvard-Smithsonian Center for Astrophysics, report that
inspection of a CCD spectrum (range 330-760 nm), obtained on Nov. 5 UT with
the 10-m Keck I telescope (+ LRIS), shows that 2010jj (CBET 2530) is a
type-IIn supernova.  The object exhibits a relatively featureless, very blue
continuum with intermediate-width (FWHM about 1800 km/s) Balmer emission lines
superposed.  He I 587.6-nm emission is also visible.
