Abstract
During the periods of meteor shower maxima in 2019–2023, small variations in the intensity of solar radiation were noted (F10.7) in fractions of a percent of the background, calculated in a sliding 5-day window. Estimates of variations in the normalized F10.7 according to the “old” (before 2006) dates of meteor showers. With the transition to new dates of meteor shower maxima, variations in magnetic activity indices disappeared. The filtering effect of meteoric dust on the regulation of variations in solar UV radiation has been proven. An increase in the intensity of UV radiation on the dates of maxima of strong meteor showers has been confirmed by measurements in 2019 at the Russian Antarctic station Novolazarevskaya.
期刊介绍：
Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
