Short summary

This paper deals with historical auroral photographs taken at the Sodankylä Geophysical Observatory (Finland) in 1927–1929. These photos are the first ones taken in Finland. The work was a co-operation with the Norwegian auroral team and Carl Störmer. The auroral material was recently found in the archive of the Finnish Meteorological Institute and is now published for the first time for the international scientific community.
