Wave-length of the Green Auroral Line Determined by the Interferometer

Article metrics


SOME years ago Babcock1 gave results of accurate measurements with an interferometer method of the green line which appears in the light from the night sky. We have reason to believe that this line is identical with the strong green line appearing in the auroral spectrum; but on account of the great interest attached to this line it will be of importance to measure accurately the wave-length of the green line from the aurora itself in order to settle the question as to the identity of the two lines.
