Description:
Multiwavelength Sun The solar chromosphere is a dynamic layer of the Sun’s atmosphere, and its appearance changes depending on the observed wavelength—meaning the element being visualized in that layer. H-Alpha (656.3 nm - red): Highlights active regions and plasma dynamics. Best reveals filaments and prominences. CaK (393.4 nm - near-ultraviolet): Better shows the interaction between the magnetic field and the chromosphere. Displays a more granular structure compared to H-Alpha. In this panel, from the top left: prominences in H-Alpha, full disk in CaK, active region AR4012 in CaK and H-Alpha.
