The solar eclipse of 30 June 1954 was observed in the neighbourhood of Helsinki on the frequency 81·5 Mc./s. [1]. At the maximum of the optical eclipse 90 % of the solar diameter was occulted by the moon. We may accordingly assume that on the wave-length of observation the eclipse was nearly central. Further, the angle between the orbit of the moon and the solar equator was only 12°.
