Abstract

Supernova SN 2004dj in the nearby spiral galaxy NGC 2403 was detected optically in 2004 July. Peaking at a magnitude of 11.2, this is the brightest supernova detected for several years. Here we present Multi-Element Radio Linked Interferometer Network (MERLIN) observations of this source, made over a 4 month period, that give a position of R.A. = 07h37m17.s044, decl. = +65 35' 57".84 (J2000.0). We also present a well-sampled 5 GHz light curve covering the period from 2004 August 5 to December 2. With the exception of the unusual and very close SN 1987A, these observations represent the first detailed radio light curve for the prompt emission from a Type II-P supernova.
