Derivation of Einstein Effect from Eclipse Observations of 1936

Abstract

THE total solar eclipse of June 19, 1936, gave Japanese astronomers an excellent opportunity for solar research. The central line ran just parallel to the north-eastern coast of Hokkaido, facing Okhotsk Sea. More than twenty sites were occupied by Japanese and visiting observing parties. Our party, being the expedition from the Tohoku Imperial University at Sendai, decided to make observations at Kosimizu, the co-ordinates of which are: astronomical longitude: 144° 28′ 3″ E. = 9h. 37m. 52˙2s. E. astronomical latitude: 43° 51′ 21″ N.
