Abstract
THIS is an elaborate account of observations made to determine the height of the aurora, by the method originally devised by Störmer, and used by him in 1910. The method consists in photographing the aurora simultaneously at two stations some miles apart, and determining its parallactic shift relative to the stars. In the present work the authors employed a base line of 12.5 kilometres, much larger than the base of only 4.5 kilometres used by Störmer in his first experiments.
