A labeled (the best I can discern) close-up of the absorption spectrum of the partially eclipsed Sun. Created with a linear 500 lines/mm diffraction grating. You can see the dark absorption lines, including many of the primary Fraunhofer lines. The lines are due to atoms of specific elements in the solar atomosphere absorbing light emitted by the photosphere, the solar "surface." G is due to iron and calcium, F is from hydrogen, E is from iron, and D is from sodium.
