WebThis paper describes develop of a two channel echelle spectrograph, Solar Chromospheric Flare Spectreograph (SCFC), to observe the optical spectra at the locations of ares and explosive events on the Sun. The SCFS will record are spectra in two channels in the wavelength range of 350-890 nm, which has several chromospheric spectral lines.

It is found that a downward motion in the flare chromospheric region is the cause of the red-shifted emission streak.
WebFeb 12, 2024 · 1 INTRODUCTION. Solar flares can have an impact on all layers of the solar atmosphere. There are strong signatures from the mid-upper chromosphere, transition region, and corona, but enhanced emission corresponding to excitation of the chromospheric temperature minimum region (TMR) and possibly the photosphere is … WebAug 22, 2024 · The chromosphere is a highly dynamic outer plasma layer of the Sun.

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 …
