The night sky on the night of the Carrington Event — 1 September 1859

On the morning of 1 September 1859 Richard Carrington, sketching sunspots at his private observatory in Redhill, Surrey, saw a brilliant white-light flare — the first solar flare ever recorded, also seen by Richard Hodgson. About 17 hours later the geomagnetic storm reached Earth: auroras were seen as far south as the Caribbean, and telegraph systems failed across Europe and North America.
