Abstract:

The results of studies of the emission spectra of the Earth’s atmosphere in the ultraviolet (UV) and visible spectral regions are presented. The input window of the spectrometer was directed to the Sun or located at different angles to the axis passing through the center of the solar disk. For the first time, a Vavilov–Cherenkov (VCh) emission spectrum was recorded with a standard spectrometer in the region 200–300 nm. The threshold energy of electrons for the occurrence of VCh emission in air and the maximum angle of propagation of VCh emission with respect to the direction of electron motion are calculated. It is assumed that the VCh emission occurs when high-energy particles of the solar wind are braked in the Earth’s atmosphere.

Keywords:

Vavilov–Cherenkov (VCh) radiation, Earth's atmosphere, solar wind, ultraviolet radiation
