Characteristics of auroral electron precipitation at 1 geomagnetic latitude 67° over Tromsø

Key Points: • We use EISCAT UHF ISR data to study the 1-100 keV electron precipitation at 6 66.7° MLAT observed during 21 years. • The auroral electron precipitation occurrence rate as observed by the radar reaches70% in the 05–06 MLT sector of the main auroral oval. • Electron precipitation with 50...

Description
Summary:Key Points: • We use EISCAT UHF ISR data to study the 1-100 keV electron precipitation at 6 66.7° MLAT observed during 21 years. • The auroral electron precipitation occurrence rate as observed by the radar reaches70% in the 05–06 MLT sector of the main auroral oval. • Electron precipitation with 50–100 keV peak energies is more common than with 30–50 keV peak energies after 06 MLT
