Ely Observatory Solar Plates Contact Prints: from Canon William Selwyn's observatory, 1863-02-11 - 1874-02-25
The prints span an eleven year period ostensibly to record a whole solar or sunspot cycle. That the purpose of the exercise may have been to investigate the supposed effect of planetary configuration on the abundance of solar spots is indicated by the presence of charts of planetary positions pasted on the verso of the mount boards and corresponding in date precisely to the prints.

RGO 67 largely consists of a good run of contact prints from glass plate negatives of the sun produced between January 1862 and January 1872. The most significant breaks are December 1862-May 1863 and August-September 1872. Additionally there are a handful of glass plate negatives and contact prints produced in 1858-9, and one further negative dated 1866. The sequence of images is essentially continued by RGO 51: RO and RGO Solar Plates Contact Prints.
RGO 57 contains drawings of sunspots showing their development, size and grouping, with tables recording the number of sunspots for each year.
