Supernova 2004dj in the nearby spiral galaxy NGC2403 was detected opticallyin July 2004. Peaking at a magnitude of 11.2, this is the brightest supernovadetected for several years. Here we present Multi-Element Radio LinkedInterferometer Network (MERLIN) observations of this source, made over a fourmonth period, which give a position of R.A. = 07h37m17.044s, Dec=+65deg35'57.84" (J2000.0). We also present a well-sampled 5 GHz light curvecovering the period from 5 August to 2 December 2004. With the exception of theunusual and very close SN 1987A, these observations represent the firstdetailed radio light curve for the prompt emission from a Type II-P supernova.
