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 … 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 …
Solar flares: What are they and how do they affect Earth?
WebApr 11, 2024 · One is based on the evaporation process during the flare, which can transport the chromospheric fractionated plasma very quickly to the corona in the decay phase of the flares. The other scenario is based on the evaporation process as well as the flare-driven Alfvén waves. In the decay phase, the reflection of the high amplitude flare … 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 razor tooth slime encrusted bone munchers

WebDec 19, 2024 · Asymmetries of chromospheric lines emitted by the flaring plasma have been observed for more than half of the century. After the solar spectrographs were developed in order to produce the solar spectrum with sufficient spectral resolution, observers noticed that the line profiles emitted during solar flares are not symmetric (Fig. … WebAug 22, 2024 · The chromosphere is a highly dynamic outer plasma layer of the Sun. Its physical processes accounting for the variability are poorly understood. We reconstructed the solar chromospheric flare...
