RO and RGO Solar Plates Contact Prints, 1873-06-02 - 1972-08-02
Scope and Contents
The 1955 prints are of images made at different times of day from the plates in RGO 50 and thus do not replicate that series. The 1956-72 prints were made from plates extant in RGO 50. Gaps in the sequence of RGO 50 were filled by sourcing plates from other observatories and thus the prints in RGO 51 also include some images created in locations other than Greenwich and Herstmonceux.
From the early 20th century the prints show the hand drawn circles, arrows and reference codes made on the glass plate negatives to mark sun spots and foculae.
