On the spectroscopy of auroral green line radiation

Abstract

In a recent paper by the authors on “Spectroscopy of the Light from the Night Sky,” a description was given of the development and the construction, with optical details, of a high light power spectrograph suitable for photographing the spectrum of the light of the moonless night sky and the spectra of auroral displays. Preliminary experiments were carried out with this instrument in England and in Canada, and a considerable number of spectrograms recorded with the instrument were reproduced and included in the paper.
