In 2001, we carried out a series of polarimetric observations of the SMC Wolf-Rayet binary HD 5980 near secondary eclipse, in order to study the mass-outflow of the system. Our observations revealed the presence of intense density enhancements along the poles and equatorial plane, that fluctuate on a very short timescale.
