Scope and Contents A set of miscellaneous drawings relating to RGO Herstmonceux and also the Roque de los Muchachos Observatory, La Palma. They were originally rolled together in three rolls labelled 'MT Miscellaneous RGO Tracings (not microfilmed)'. The drawings have been arranged in sets according to drawing number where possible; drawing number usually corresponds to size ('V' being the largest and 'Z' the smallest). There are distinct V, W, X, Y and Z sized drawings, and four additional sets, including a...

Scope and Contents In 1969, a sub-committee of the Astronomy, Space and Radio Board (ASRB) of the Science Research Council was established to examine the SRC’s future support for astronomy in the Northern Hemisphere, with a view to establishing a Northern Hemisphere Observatory (NHO). One task of the Northern Hemisphere Review Committee (NHRC) was to obtain the views of senior British astronomers within the SRC (including staff of the RGO and ROE) and in universities on the proposed NHO. File RGO...

Scope and Contents The Olsen interviews provide contemporary accounts of the progress of the establishment of the Northern Hemisphere Observatory. These tapes are compiled from a series of short interviews originally recorded by Jim Olsen in Los Llanos and on the mountaintop in 1974-1976. All the interviewees were associated with astronomical site testing campaigns being carried out at Fuente Nueva on La Palma. The tests on La Palma were very successful and the observatory was eventually established as the...
