Supernova 2010ea.

BALAM D.D.

Abstract (from CDS):

After posting on the Central Bureau's unconfirmed-objects webpage, D. D. Balam, Dominion Astrophysical Observatory, National Research Council of Canada, reports that images (limiting mag about 20.5) taken in twilight with the 1.82-m Plaskett Telescope on June 8.23 UT show 2010ea at magnitude V = 18.34, with colors B-V = +0.2 and V-R = +0.4 (SDSS DR6 magnitudes were converted to Kron-Cousins using the conversion formulae of Chonis and Gaskell 2007, A.J. 135, 264), and located 0".2 west and 11".0 south of a galaxy with Sloan Digital Sky Survey magnitude g = 16.61 and redshift z = 0.03 (designated SDSS J12452954+5352002). Balam adds that there is also a very faint (g = 21.4, r = 21.5) galaxy (or possibly a not in a spiral arm of the brighter galaxy) located near, but not at, the source position (SDSS J12452956+5351470); this fainter "galaxy" or knot is located 0".2 east and 13".2 south of the brighter galaxy (and 0".4 east and 2".2 south of 2010ea).
