Expectancy of Clear Days in the Central Zone of the Total Eclipse of the Sun June 30, 1954, in Sweden

Abstract

The occurrence of the total solar eclipse in 1954, visible in southern Sweden, has raised the question regarding the cloudiness conditions which may be expected in this part of the country at the time of the eclipse. A detailed investigation of the average sunshine conditions at Swedish stations situated along the track of the totality has therefore been made. From this is concluded that the coastal regions are decidedly more favourable than the inland. A comparison between the western and eastern coasts leads to the conclusion that the average cloudiness at 14h, the hour of observation nearest to the totality, is slightly higher on the West coast than at locations on northern Öland and southern Gotland. Regarding the number of clear sky days at different places the coasts are also more favourable than the inland, and of those the northern part of Öland seems to be considerably more favourable even than the outer part of the West coast. The statistics refer to observations at 14h June 20–July 10 in the years 1931–1950.
