SUPERNOVA 2010mc
     Eran O. Ofek, Weizmann Institute of Science, Israel, reports the
discovery of a supernova (mag about 20.2) on two r-band CCD images (limiting
mag 20.9) taken on 2010 Aug. 20.2 UT with the 1.2-m Oschin telescope at
Palomar Observatory in the course of the "Palomar Transient Factory" survey.
The new object is located at R.A. = 17h21m30s.68, Decl. = +48d07'47.4
(equinox 2000.0), which is about 2" east of the nucleus of the presumed host
galaxy.  The object was not detected in a deep reference image of this field
obtained in 2009 (limiting magnitude 22).
     D. A. Howell and D. Murray report that optical spectroscopy (range
350-1000 nm), obtained on 2010 Aug. 26 UT with the Gemini-North telescope
(+ GMOS) showed that 2010mc was a type-IIn supernova at redshift z = 0.035.
The Gemini-North classification spectrum is posted at the following website
URL:  http://www.weizmann.ac.il/astrophysics/wiserep/; classification was
made via SUPERFIT (Howell et al. 2005, Ap.J. 634, 1180).
