5 photographs of the sun, gelatin silver prints, approximately 200 x 150 mm to 160 x 150 mm, Greenwich, England and Kodaikanal, India, 1906 to 1917, all hand-captioned on verso, three images credited to John Evershed (dated 1916-1917), while the other two are credited to the Royal Observatory. All toned, with browning to paper, light wear to edges. John Evershed was born in England but became director of the Kodaikanal and Madras observatories in India, where he made the first observation of the radial motion of gases in sunspots which came to be known as the Evershed effect. He retired in 1923 and returned to England where he continued his solar observations on his own. He was awarded the Gold Medal of the Royal Astronomical Society and was made a Companion of the Indian Empire upon his retirement.
