Fig. 6.
Line scan of NIR Ca II at 17:21:42 UT during best seeing conditions. The scans show filtergrams at the wavelength positions Ca II ± 0.75 Å, Ca II ± 0.25 Å, and Ca II ± 0.15 Å and the line-core filtergram (λ0 = 8542.21 Å). The line core is located in the chromosphere, whereas the line wing filtergrams refer to successively lower regions in the solar atmosphere. A movie associated to this figure is available online.
