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…
Long-term trends in the solar activity. Variations of solar indices in last 40 years
E. A. Bruevich, V. V. Bruevich
The analysis of long-term variations of several solar activity indices (AI) since in last 40 years has been performed. We studied the AI which characterize the fluxes from differen…
Levels of chromospheric and coronal activity in Sun-like stars and various types of dynamo waves
E. A. Bruevich, M. M. Katsova, D. D. Sokolov
We analyze the X-ray emission and chromospheric activity of Sun-like stars of F, G and K spectral classes (late-type stars) studied in the framework of the HK project. More powerfu…
Powerful solar flares in September 2017. Comparison with the largest flares in cycle 24
E. A. Bruevich, V. V. Bruevich
Solar flare activity in cycle 24 is studied. Satellite observations of x-ray fluxes from GOES-15 and UV emission lines from the SDO/EVE experiment are used. The most powerful flare…
New classification parameter of solar flares based on the maximum flux in soft X-rays and on duration of flare
Elena Bruevich
Solar flare activity is characterised by different classification systems, both in optical and X-ray ranges. The most generally accepted classifications of solar flares describe im…
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…
