SUPERNOVA 2013ed IN SDSS J161623.74+515313.9
Further to the supernova discovery by Tom Boles announced on E-Circular
2931, spectroscopic confirmation has resulted in its designation SN 2013ed.

Dave Balam, Dominion Astrophysical Observatory, National Research Council of
Canada et. al. report that a spectrogram (range 369-700 nm, resolution 0.3
nm) obtained on 2013 July 19.29 UT with the 1.82-m Plaskett Telescope of the
National Research Council of Canada, shows it to be a type-Ia supernova near
maximum light.  

M. Dennefeld, Institut Astrophysique de Paris et. a., report that a
spectrogram obtained with the Nordic Optical Telescope (+ ALFOSC) on 2013
also shows it to be a typical type-Ia supernova with strong Si 635.5-nm
absorption.
