The authors present the results of photometric observations of the optical counterpart of the recurrent X-ray transient A0538-66. Three outbursts were observed in 1982 April and May. During the period 1982 October - 1983 February the source did not show outbursts. Combining their data with those of Densham et al. the authors find evidence for a secular decrease of the size of the outbursts throughout a period of activity. The interoutburst UBV properties of A0538-66 likewise show a progressive change. During the off-state A0538-66 shows small-amplitude variability, similar to that observed in some 'normal' Be stars. In the (V, B-V) and (U-B, B-V) diagrams both these variations and the secular variations of the previous interoutburst data lie along tracks which appear to be connected.
