There is a project going on, involving several observatories, which is
. . . Emission lines are those for which
the radiant flux is greater than the flux at adjacent wavelengths.
they show as peaks in a spectrum of intensity plotted against
wavelength. The Sun has none to speak of in the visible, and
certainly not in the disk for hydrogen, which is abundant in the
chromosphere. Emission lines of hydrogen can be seen in solar
prominences during a total solar eclipse. In fact they look red.
Those with an intense interest in the solar spectrum might like
