Chromosphere size
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 … WebJun 8, 2024 · The chromosphere is best imaged in the H-alpha emission wavelength. The challenge is that the underlying photosphere completely overpowers the signal from the chromosphere. The solution is to image as precise as possible in the H-alpha wavelength. The concept is similar to using narrowband filters when the full moon is out.
