WebThis low energy X-ray emission seems to indicate that the heating source was around the null point and along the outer spine, while it did not show any spatial correlation with the chromospheric emission, contrarily to what observed by Yang, Guo & Ding (2015) in a X-class circular ribbon flare occurred on 2013 October 23.
WebWe present observations of optical spectra of a flare in which blue line asymmetry was seen for more than 4 min close to the flare onset. The maximum blue asymmetry coincided with the maximum of a hard X-ray and microwave burst. We discuss possible interpretations of the blue asymmetry and conclude that the most plausible one is electron-beam heating … WebRed-shifted emission streaks of Hα line are found at the initial phase of almost all flares which occur near the disk center, and are considered to be substantial features of the red asymmetry. It is found that a downward motion in the flare chromospheric region is the cause of the red-shifted emission streak.
Webthe chromospheric heating terms. Our analysis includes the main bound-bound chromospheric coolers: the Ly , Caii H and K, and Mgiih and k spectral lines, and the Ca IR triplet. Due to the lack of an accurate and realistically large atomic model, our cal-culations do not include the contribution from Feiilines, which
