WebThe structure of the solar chromosphere, and in particular of internetwork regions, is still an issue of intensive scientific debate. On the one hand UV diagnostics imply a hot layer with only small temperature fluctuations, as expressed in static semi-empirical 1-D models like, e.g., FAL A, VAL C ([\astroncite Fontenla et al.1993]; [\astroncite Vernazza et al.1981]). WebAug 11, 2014 · The chromosphere is also visible in the light emitted by ionized calcium, Ca II, in the violet part of the solar spectrum at a wavelength of 393.4 nanometers (the Calcium K-line). This emission …

WebApr 12, 2024 · Estimating the longitudinal magnetic field in the chromosphere of quiet-Sun magnetic concentrations ... The longitudinal magnetic field in each considered plasma structure correlates with its size. Using a spectral range restricted to the line core leads to chromospheric longitudinal fields varying from ∼50 G at the edges to 150–500 G at ... http://www.astronomynotes.com/starsun/s2.htm highlight of the year

WebThe chromosphere represents the dynamic transition between the cool temperature minimum of the outer photosphere and the diffuse million-degree corona above. It derives its name and pink colour from the red … Websize in the raster scan, and the sampling along the slit were set to 0″.16. Each raster scan consisted of 250 steps. The observed field of view is 40″ by 40″. The observations were done with the 308 subaperture adaptive optics. The spatial resolution of imaging on this day is estimated at twice the step size, which is 0″.32.
