We have recently used the PISCO and VATPOL Polarimeters at the MPI (Chile) and CASLEO (Argentina) 2.2 m telescopes to monitor over several weeks the brightest WR+O systems fainter than 9th magnitude in the Galaxy (V filter) and LMC/SMC (GaAs tube without filter). Each data point is accurate to ~ 0.02% in polarization P.
