Flux Variations in Lines of Solar EUV Radiation Beyond Flares in Cycle 24

E. A. Bruevich, G. V. Yakunina

Studies in the extreme ultraviolet (EUV) and X-ray ranges of the solar spectrum are important due to the active role of radiation of these ranges in the formation of the Earth's io…

Cyclic Variations in the Solar Radiation Fluxes at the Beginning of the 21st Century

E. A. Bruevich, V. V. Bruevich, G. V. Yakunina

The solar activity in the current, that is, the 24-th, sunspot cycle is analyzed. Cyclic variations in the sunspot number (SSN) and radiation fluxes in various spectral ranges have…

Flare activity of the Sun and variations in its UV emission during cyrcle 24

E. A. Bruevich, G. V. Yakunina

The flare activity and the ultraviolet emission of the sun during its 24-th cycle are analysed. As compared to cycles 21-23, where the most powerful flares were observed during the…

General trends in the changes of indices of solar activity in the late XX - early XXI century

E. A. Bruevich, G. V. Yakunina

The analysis of the observations of solar activity indexes SSN (NOAA Sunspot Numbers), the radio flux at a wavelength of 10.7 cm (F10.7) and the solar constant (TSI) during the cyc…

The study of time series of monthly averaged values of F10.7 from 1950 to 2010

E. A. Bruevich, V. V. Bruevich, G. V. Yakunina

Prior to 1947, the activity of the Sun was assessed by the relative numbers of sunspots (W). The 10.7 cm radio emission (frequency of 2.8 GHz) for observations of the variability o…
