Solar flares catalog
Complex analysis of the generation of high-energy neutral radiation (gamma-quants and neutrons) during the solar flares onboard the SMM satellite has shown that this study provides important information about the generation of the solar energetic particles. The development of a complex program of the studies of solar activity and its influence on the near-Earth space began in the USSR in the middle of 80s of the 20th century. It resulted in a development of a number of satellites of CORONAS series. A set of scientific instruments SCR (Solar Cosmic Rays) was developed by the scientists of SINP MSU and IEP SAS in order to study relations between the radiation conditions in the near-Earth space and solar activity. This instrument was installed onboard the satellites CORONAS-I and CORONAS-F launched to the orbit on March 2, 1994 and July 30, 2001, respectively. It consisted of the following three instruments:
SONG (SOlar Neutrons and Gammas) instrument is intended for registration of X-rays and gamma-emission within the energy range of 30 keV — 200 MeV, and neutrons with energies over 20 MeV. Besides, this device could measure the flux and the spectrum of electrons within the range of 2–108 MeV and proton flux with energies > 75 MeV.
MKL (Russian abbreviation for Monitor of Cosmic Rays) instrument is intended for registration of electron flux within energy range of 0.3–12 MeV and proton flux with energies from 1 MeV up to ∼ 90 MeV.
CCR-3 (Composition of Cosmic Radiation) instrument measures the densities of the fluxes of nuclei within the charge range 1–10 and energy range from few up to dozens MeV per nucleon: 1.5 < E < 19 MeV/nucleon for the nuclei 1Н and 4Не; 3.7 < E < 46 MeV/nucleon for the nuclei up to 20Ne.
