Abstract
different solar proton events in 24th solar cycle for several years are presented. Data from spectrometers placed onboard Russian spacecrafts Electro-L and Meteor-M, functioning at geostationary and polar orbits correspondingly are used, and also free access data from GOES and POES are used.
Solar proton fluxes were determined for different events for several years in 24th solar cycle at geostationary orbit according to measurements of Electro-L and GOES spacecrafts as well as at polar orbit according to measurements of Meteor-M.
Single events upset rate values were calculated for different events in different orbits using measured and model solar proton spectra. Analysis results of comparing of solar proton events frequency and magnitude for different years of 24th solar cycle were discussed. We show that solar proton events contribution vary considerably depending on the event and the orbit type.
