2 PROTON AND ELECTRON AURORA OVER EISCAT: OPTICAL SIGNATURE AND ASSOCIATED IONOSPHERIC PERTURBATIONS
For moderately magnetically disturbed conditions, the EISCAT radar site near Tromsø, Norway, is located on the equatorial edge of the afternoon auroral oval for several hours, where energetic protons are a dominant particle energy source. A unique signature of proton precipitation is the Doppler-shi...
