Abstract:
A study of the polar coronal rays made on two eclipse photographs is presented. From the frequency distribution of polar rays, it is shown that the maximum distribution of polar rays occurs in an annular zone arround 10/supo/ from the poles and a minimum at the poles. From the orientation of the polar rays the length of the hypothetical bar magnet has been determined. A variation in the length of the hypothetical bar magnet with the phase of solar activity cycle is confirmed.
