The programme presents research on the sun’s aurora, solar constant (energy output), sunspot cycles, solar winds, coronal holes and tree-ring analyses with historical scientific records to show how the sun’s changes affect the earth’s weather. Dr. Charles Greeley Abbot believed the sun undergoes cyclic changes in output, which produces long term effects on the earth’s weather.

Evidence is presented that links the drought cycle with the number of magnetically-hyperactive ‘sunspots’ (blemishes on the surface of the sun) - they reach their peak every 11 yrs. Sunspots also are linked to the Aurora Borealis displays and the variance of the ‘Ozone Layer’ around our atmosphere. The 11yr sunspot cycle suggest that the sun is not as constant a star as we assume, and the energy output by the sun may vary over the years to explain changing weather.

Horizon produced their programme from a film written and directed by Ben Shedd and Graham Shedd. This film perhaps editted differently was broadcast abroad under the title “The Sunspot Mystery”, and subsequently that version was shown abroad on a commercial cable channel. It is the cable version, probably missing a number of minutes, sacrificed to advertisement time, that has been spliced without the ads into the file provided here.
