An H-alpha image taken by the Big Bear Solar Observatory. H-alpha is a particular part of the visible spectrum: one of the spectral lines produced by hydrogen. H-alpha light is produced in the chromosphere, above the surface of the sun, so it provides us with a clearer picture of activity above the solar surface. Filaments and prominences are both seen more clearly in H-alpha, while sunspots are somewhat visible.
