Details:
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.
