Divided Aurora Rays with one Part in the Sunlit and another in the Dark Atmosphere

Abstract

ON October 11 last a fine aurora was photographed from eight of my aurora stations in southern Norway. The stations Kongsberg, Tömte and Askim, forming a triangle with sides 105 km., 80 km. and 85 km., worked together with my station on the eastern roof of the Oslo Observatory ; all four were connected by telephone and took simultaneous pictures in continual succession as rapidly as possible. Three other stations, Tuddal, Lillehammer and Oscarsborg, forming a triangle with sides 178 km., 159 km. and 101 km., were in the same manner connected with my other station on the western roof of the same Observatory and worked independently of the first set.
