Abstract
It is now established that auroral emissions as measured from ground are polarised. The question of the information given by this polarisation is still to be explored. In this article, we show the results of a coordinated campaign between an optical polarimeter and several ground based instruments, including magnetometers, the EISCAT VHF radar and complementary luminance meters in the visible domain (Ninox). We show that in the E region, the polarisation is a good indicator of the ionospheric currents, velocity and dynamics.
