Abstract

We presented the results of analysis of electromagnetic radiation in the frequency range from 20 to 1040 kHz, detected on the WIND satellite during 2004–2021. A comparison of this radiation with the results of measurements on near-Earth spacecraft confirmed the previous conclusion that the radiation received on the WIND satellite is auroral kilometric radiation (AKR) and its source is in the Earth’s magnetosphere. A statistical analysis showed that a significant part (up to 70%) of AKR reaches the L1 libration point, where the WIND satellite is located, and that the AKR spectrum noticeably transforms and the spatial distribution of radiation occurrence rate is nonuniform and changes in the course of the solar cycle.
