Kew Observatory solar photographs, 1858 - 1872
Scope and Contents
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.

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.

Other Finding Aids
A handlist is kept in the Manuscripts Reading Room but contains a considerable number of keying error rectified in this electronic version. A tabulated catalogue, combined with other RGO solar image lists, and which may be sorted by various data e.g. former reference.
Immediate Source of Acquisition
The items were probably transferred from Kew to the Royal Observatory, Greenwich, before being deposited in the R.G.O. Archives.
The online catalogue for Janus was compiled from an existing list in November 2008 by Zoe A. Rees, Department of Manuscripts and University Archives, and was emended in July 2009.
