. From February 1942 Hey's task was to work on radar anti-jamming methods; for a year German jamming of Allied radar had been a problem and the escape of three German warships through the English Channel, aided by enemy

jamming from the French coast, had highlighted the problem. On 27 and 28 February 1942 Hey had reports from sites across Britain of severe noise jamming of anti-aircraft radars in the 4–8 m range. Realising that the direction of maximum interference seemed to follow the Sun, he checked with the

and found that a very active sunspot was traversing the solar disc. He concluded that a sunspot region, which was believed to emit streams of energetic ions and electrons in magnetic fields of around 100 G (gauss), could emit metre-wave radiation. This was the first discovery of a specific astronomical radio source. Later in 1942, G.C. Southworth in the USA also linked the Sun with radio noise, this time in the centimetre-wave region. Later, in 1944–1945, Hey used radar to track the paths of

had found in the 1930s. Hey's results of 1942 and 1944 could not be published until after the war. From 1945 to 1947, Hey used AORG's radars in Richmond Park to research his wartime radio astronomical discoveries further. The Richmond Park installation thus effectively became the first radio observatory in Britain. Hey's main colleagues in this work were John Parsons (1918–1992), an electrical and mechanical engineer; Gordon Stewart (1919–2003), an electrical engineer; and James Phillips (1914–2003), a mathematician, who like Hey had been a schoolmaster before the war. In 1946 the Sun became active again, and the group confirmed sunspots and solar flares as the source of the emissions. In 1945 and 1946 they confirmed radar echoes from meteors, and derived methods to derive meteor shower radiants from the echoes, so discovering the first daytime meteor shower. In 1945 and 1946 they mapped the intensity of cosmic radio noise across the sky. In February 1946 they discovered a strong source in Cygnus which scintillated rapidly. Hey realised that the scintillation meant that the source must be compact, and suggested that it was a 'radio star'. It was later shown to be

Personal life

Brought up in a church-going Wesleyan Methodist family, Hey became an agnostic in his teenage years, and remained so for the rest of his life. He met his wife, Edna Heywood, when they were both students at Manchester University. They married in 1934. The couple moved to Eastbourne in 1969, following Stanley Hey's retirement. Edna died in September 1998, 12 years after having a severe stroke.
