The evolution of the radio flux densities is discussed in Section 2. The sequence of images is extended to late-2000 and discussed in relation to recent optical and X-ray imaging in Section 3. Future prospects are canvassed in Section 4.

Evolution of Radio Flux Densities and Spectral Index
====================================================

Flux density monitoring observations of SNR 1987A are made using the ATCA at 4 – 6 week intervals using one of the 6-km array configurations. Observations are made simultaneously at two frequencies, either 1380 and 2496 MHz (2368 MHz before mid-1997) or 4790 and 8640 MHz. A 128-MHz bandwidth is observed at all frequencies. The two frequency pairs are observed alternately, with 20 min on SNR 1987A and 3 min on phase calibrators before and after the SNR observation, with a total observation time typically of 12 hours. All observations are made with a J2000 pointing and phase centre of R.A. $05^{\rm h}\;35^{\rm m}\;27\fs90$, Dec. $-69^{\circ}\;16'\;21\farcs6$, approximately $10''$ south of the SN 1987A position (Reynolds et al. 1995). The phase calibrators are PKS B0530–727, PKS B0407–658 and (at 4790/8640 MHz) PKS B0454-810. Flux calibration is relative to PKS B1934-638, assumed to have flux densities of 14.95, 11.14, 5.83 and 2.84 Jy
