An example of the AKR (Auroral Kilometric Radiation) recorded by the POLRAD radio-spectro-polarimeter. The 3 perpendicular components of the electric field are presented in the range from 4 kHz to 1 MHz , while crossing the morning sector of the auroral region (3.00 - 5.40 MLT) at the altitudes from 14441 to 18392 km. The lower limit of the AKR was at 150 kHz, while the maximum power was received at a typical range from 200 to 400 kHz. ...
