APOD #5

On November 3, there was a brief total solar eclipse in Gabon, Uganda, Africa, that caused for the Sun's visible spectrum to change from absorption to emission. The normally dominant absorption spectrum was blocked by the moon, allowing for the spectrum, spread by diffraction grating, to be seen as individual eclipse images at each wavelength of light. The brightest in the image are the red alpha emission brought by Hydrogen and the yellow emission by Helium.
