SN 1994D Supernova Classification at the CfA

This page lists supernovae discovered in 2010 and classified by the CfA SN Group
Look for updates soon (06/16/11) including spectra of all CfA classifications.

SN classified in previous years are found here: [Archive (1996-2009)]

All supernovae are classified using the SuperNova IDentification code (SNID) [Blondin & Tonry (2007)]
