Zusammenfassung: | The paper presents an analysis of a series of observations of the full H-alpha line profile in the solar chromosphere. The analysis is based on data from the spectroheliograph patrol telescope developed at the Kislovodsk Mountain Astronomical Station, which has been in operation since 2015. The telescope conducts continuous observations with a scanning time of the entire solar disk of about 1 min. The problem of measurement of the parameters of the H-alpha line with various methods of profile approximation is considered. The possibility of determining the Doppler shift in the H-alpha line with the use of a convolutional, artificial neural network has been studied. Also considered are the characteristic forms of the H-alpha profile in active regions of the Sun and the evolution of the line profile and Doppler velocities during the formation of a solar flare on the example of an X-class flare. |
