PROPERTIES OF ULTRAVIOLET EMISSION AT DEVELOPMENT OF SOLAR FLARES
Ключевые слова:Solar flares, photometry, emission of flares, gamma rays.
By means of processing photoheliograms in the λ1700Ǻ ultraviolet emission (temperature minimum,
upper photosphere) obtained on the Solar Dynamics Observatory (SDO) spacecraft, the behavior of the relative
intensity of bright plasma at the level of the photosphere during the development of impulsive phase of solar flares
was studied. The interrelation of the course of change in flare ultraviolet emission with the profile of time derivative
of the X-ray flux (1–8) Ǻ and with the value of enhancement in the density of electrons arising at development of
flares has been revealed.
