During the long runs carried out at EISCAT, plasma line are regularly measured. They are mainly used for calibration of the ion line analysis, but give also information on the suprathermal electrons in the ionosphere. By monitoring both the upshifted and downshifted lines simultaneously, one can from differences in power and frequency shift deduce currents along the radar line-of-site. From the long run in March-April 2006 and the present one year IPY run, started 1 March 2007, the daily and day-to-day variations of direction and strength of field aligned currents over the EISCAT Svalbard Radar are presented.
