We present ASCA observations made in February 1995 around the time of a predicted outburst from the 16.65 day period recurrent transient A0538-66 together with simultaneous optical photometry. Optical spectroscopy was also obtained near a predicted outburst approximately two months earlier. We find that A0538-66 is active, both in X-rays and optically, although at a much lower level than during the largest super-Eddington outbursts that have been seen in the past. The optical spectra show variable Balmer emission but not the strong HeII 4686\AA\ emission that accompanies large outbursts.
We consider X-ray production processes that may produce the observed behavior. In particular accretion onto the magnetosphere rather than the surface of a neutron star is discussed.
