1 September 1859: the ‘Carrington Event’, the biggest solar storm ever recorded

On this day in 1859, a huge mass of magnetic particles erupted from the sun and hit the earth, knocking out telegraphs and putting on a spectacular display in the skies.

The morning of 1 September 1859 was lovely and sunny in the south of England. That was good news for amateur astronomer Richard Carrington, who had a particular fondness for observing the sun. That day, he went up to his private observatory, pointed his telescope at the sun, and began to sketch the sunspots. What he saw next got him very excited indeed.

"Two patches of intensely bright and white light broke out" of the sun, wrote Carrington, and hurled invisible particles towards the earth. It didn't take long for the particles to smash into our magnetic field and light up the skies. That night, bright red and green auroras could be seen as far south as Cuba.

Ben studied modern languages at London University's Queen Mary College. After dabbling unhappily in local government finance for a while, he went to work for The Scotsman newspaper in Edinburgh. The launch of the paper's website, scotsman.com, in the early years of the dotcom craze, saw Ben move online to manage the Business and Motors channels before becoming deputy editor with responsibility for all aspects of online production for The Scotsman, Scotland on Sunday and the Edinburgh Evening News websites, along with the papers' Edinburgh Festivals website.

Ben joined MoneyWeek as website editor in 2008, just as the Great Financial Crisis was brewing. He has written extensively for the website and magazine, with a particular emphasis on alternative finance and fintech, including blockchain and bitcoin. 

As an early adopter of bitcoin, Ben bought when the price was under $200, but went on to spend it all on foolish fripperies.
