X-ray of the 2017 September 10 Solar Flare

Abstract

Abstract The analysis of soft and hard X-ray radiation of behind the limb solar flare SOL2017-09-10T15:35 according to the RHESSI data was carried out. The plasma parameters were determined: emission measure, temperature, density. Sources of hard X-ray radiation >30 keV are observed for several hours after the maximum of the flare. It indicates the long-term processes of acceleration of electrons in the solar corona. The rise of the X-ray source during 6.5 hours was ∼70 arcsec. It was proposed also an alternative method for determining the plasma density, based on cross-correlation analysis of time series (time delay method).
