Dark absorption lines in the solar spectrum seen against the bright continuum spectrum of the photosphere.

Associated with specific atomic energy level transitions, these absorption features occur as a consequence of wavelength variations in the atomic opacity and the outward decrease in photospheric temperature (after the German physicist Joseph Fraunhofer, 1787–1826).
