Radio supernova 1987A at 843 MHz

We report here the flux densities of the evolving radio source SN 1987A at 843 MHz measured from observations made with the Molonglo Observatory Synth esis Telescope between 1994 September and 2000 May. The radio light curve s hows that the rate of increase of the flux density jumped markedly around d ays 2800-3000 (i.e., in the first half of 1995) and that since then the rad io evolution has been remarkably well fitted by a simple linear increase of 62.7 +/- 0.5 mu Jy day(-1). We discuss in detail the relationship between the radio light curve and the recent brightening of the system at optical w avelengths.
