Solar Flares in the Euv and X-Ray Ranges According by Sdo and Timed Satellite Data

Abstract

In this work observational data of the Solar Dynamics Observatory (SDO) and TIMED spacecraft (Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics) have been studied simultaneously with radiation in the 0.1-0.8 nm X-ray range from GOES-15 satellite observations. Fluxes in the Lyman series spectral lines and their variations in solar cycles 23 and 24 are analyzed. The analysis of five flares (X-class) according to GOES-15 and SDO/EVE observational data in 24-th cycle of solar activity (2011)(2012) has been done.
