Abstract
WE detected a second outburst with a high degree of linear polarisation from Cyg X-3 in August 1975, following the alert by Kawajiri1. The first such outburst was observed in May 1974 (refs 2 and 3). Here we report observations of both polarised outbursts as well as of an unpolarised outburst in January 1975. At 8 GHz the observed polarisation position angle was the same for both polarised outbursts. The Faraday rotation measure associated with the source is much larger than previously reported2. We suggest that the orientation of the magnetic field in the source and the rotation measure are both stable with time. In addition, we find that the highly polarised outbursts decay significantly more slowly than the unpolarised outbursts.
