A collection of 24 photographs capturing various groups that travelled to Esashi, Hokkaido, to view solar eclipses in the late 19th and early 20th centuries. Many of the photographs feature a woman who is almost certainly Zou Yixin (1911-1997), a Chinese astronomer and professor at Sun Yat-sen University who is known to have visited Easashi as part of the Chinese team observing the eclipse on June 19, 1936. This team and a team from the Kwasan Observatory at the Graduate School of Science of Kyoto University are known to have observed the eclipse at Esashi, where the Amherst Expedition headed by Professor David Todd observed an eclipse on August 9, 1896. Several photographs of this earlier expedition are also included.
