Aurora Borealis

Abstract

AN active aurora of great brilliancy was visible here on Friday night from nine till ten p.m. The whole realm of the sky from north-west to north-east and from horizon to zenith was filled with a vaporous and highly luminous mass with streamers and rays, the light sufficing for reading moderately large type. The streamers and rays were projected from the upper edge of an arch of dark-coloured vapours resting on the northern horizon. The sky space occupied by the points of the streamers covered the constellation Ursa Major on the west, Cassiopea on the east, and the intermediate region. Among the brilliant sheaf of white streamers an occasional dark-coloured ray shot upwards from the generating arch.
