Scientific paper

Supernova 1987A in the LMC was discovered on 24 February 1987; optical observations define the geocentric time of the explosion to be between February 23.10 and February 23.443 UT. Radio emission from the supernova was detected at Australian observatories within two days of the increase in optical brightness. The authors report information obtained at four frequencies, namely 0.843, 1.415, 2.29 and 8.41 GHz. At frequencies around 1 GHz the peak flux density was about 150 mJy and occurred within four days of the supernova. The event may be a small precursor to a major flare of the type previously observed in radio supernova.
