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.

Biographical / Historical

The Kew Observatory pioneered the regular photographing of sunspot activity in the United Kingdom. The photographs were made using the Kew photoheliograph, which was designed by Warren De La Rue in 1857 for this specific purpose. The photoheliograph was transferred to Greenwich in 1873, after the Royal Society assumed responsibility for the Kew Observatory. For an administrative history of Kew Observatory see RGO 66.
