Abstract

Regarding the anomalou s distribution of ultraviolet sky radiation observed during the annular eclipse at Rebun Isla nd (N.45°15', E.141°) on May 9th 1948, an explanation wa s attempted through the calculation of the intensities of primary and secondary scattered sunlight which contains eclipse effect.
According to the result of calculation the passibility of giving rise to the anomalous peak at 15° of zenith angle wa s confirmed especially in the distribution of secondary scattering, where polarization by primary scattering played an important role more distinctly than in the normal case which was discussed previously in this series.
But a quantitative agreement was not yet achieved, which fact shows the necessity of considering the scattering of h igher orders than the second or other factors.
