Kew Observatory was originally built in 1769 for King George III, a keen amateur astronomer, so that he could observe the transit of Venus. By the mid-nineteenth century, it was a world-leading center for four major sciences: geomagnetism, meteorolog

In 1939, the British Admiralty agreed to move the Royal Observatory from Greenwich to a better site away from London. The removal was postponed due to the Second World War, and the observatory’s re-establishment at Herstmonceux Castle in Sussex in

An extensive investigation of ships’ logs, as part of the ‘Old Weather’ citizen-science project, identified a sunspot observation made from HMS Hilary on 10 February 1917. This sunspot record was accompanied by detailed meteorological records t

Sir John Herschel (1792–1871) has become so well known to historians as a trailblazer in sciences such as photography, mathematics, optics and chemistry, in addition to being the author of a semina...

Large sunspots can be observed with the unaided eye under suitable atmospheric seeing conditions. Such observations are of particular value because the frequency of their appearance provides an approximate indication of the prevailing level of solar

Traditionally, historians have taken it for granted that Britain’s National Physical Laboratory (NPL) was created as the result of demands from a “professional” body of university-based physicists for a state-funded scientific institution. Yet

As one of his first acts upon becoming Astronomer Royal in 1835, George Airy made moves to set up a new observatory at Greenwich to study the Earth's magnetic field. This paper uses Airy's correspondence to argue that, while members of the reform mov

The study of historical great geomagnetic storms is crucial for assessing the possible risks to the technological infrastructure of a modern society, caused by extreme space–weather events. The normal benchmark has been the great geomagnetic storm
