• In 2013, scholars discovered an anonymous report published in 1871 in Nature describing how a “very intense magnetic disturbance” disrupted rail travel in Exeter on the southern coast of England in October 1841.
• If accurate, this would be the earliest such account.
• However, according to a paper published in the journal Space Weather, that 1841 date is most likely a typo, with the real railway disruption occurring several years later.
• “Space weather is often discussed as a modern challenge because of our dependence on technologies such as satellites, communications systems and electricity networks,” said co-author Jim Wild of Lancaster University.
• “What this study shows is that society has been experiencing the effects of space weather on technology for almost as long as electrical technologies have existed.
