WHAT DOES SPECTROHELIOGRAM MEAN IN ENGLISH?
Definition of spectroheliogram in the English dictionary
The definition of spectroheliogram in the dictionary is an image of the sun obtained by a spectroheliograph, which shows light of a particular wavelength, such as calcium or hydrogen, and the distribution of the element over the surface and in the solar atmosphere.
