Abstract: The auroral red line at 630 nm is linearly polarized. Up to now, only its Degree of LinearPolarization had been studied. In this article, we examine for the first time the Angle of Linear Polarization(AoLP) and we compare the measurements to the apparent angle of the magnetic field at the location ofthe red line emission. We show that the AoLP is a tracer of the magnetic field configuration. This opens newperspectives, both in the frame of space weather and in the field of planetology.
