Solar Energetic Proton Fluxes in Near-Earth Space on March 13-23, 2023
Vlasova, N. A.; Bazilevskaya, G. A.; Ginzburg, E. A. +5 more
The results of studying the fluxes of solar protons with energies greater than 5 MeV in near-Earth space on March 13-23, 2023, are presented. The features of the period under study are no visible solar flare with which the beginning of the event could be associated and an untypical time profile of proton fluxes, as well as a long duration of the e…
Earth's Ionospheric Response to Solar Activity Phenomena in February-March 2023
Sheiner, O. A.; Vybornov, F. I.
As a result of the analysis of data from vertical and oblique sounding of the ionosphere in February-March 2023 using the new ionospheric index, it was found that solar coronal mass ejections (CMEs) of the loop type lead to a long-term decrease in the critical frequencies F-layer of the ionosphere, while other types of CMEs may not lead to signifi…
