Search for the relationship between background VHF radio bursts and energetic particle dynamics based on data from the MKL instrument onboard the CORONAS-F satellite

Abstract

The solar flare of November 4, 2001, at 16.03–16.57 UT (GOES soft X-ray class X1.0, optical importance 3B, and coordinates N06W180) is used as an example to investigate the relationship between sporadic VHF radio bursts and charged particle fluxes (of both solar and magnetospheric origins) at an altitude of 500 km. The radio background intensity was recorded at frequencies of 280, 300, 151, and 500 MHz by nondirectional ground-based mid-latitude radio antennas spaced ∼700 km apart. The results of our radio measurements are compared with the dynamics of 0.2–12 MeV electron and 1–5 MeV proton fluxes based on data from the MKL instrument onboard the CORONAS-F satellite (the orbit altitude and inclination are 500 km and 82.5°, respectively).
