Scientists clarify earliest recorded space weather disruption to technology
Key points
- An 1871 report described an 1841 magnetic disturbance disrupting rail travel.
- New research suggests the 1841 date was a typo.
- The Carrington Event of 1859 remains the most powerful recorded geomagnetic storm.
- Space weather has affected technology since electrical systems emerged.
Revisiting an Early Space Weather Account
An anonymous report from 1871 in Nature described a "very intense magnetic disturbance" in October 1841 that disrupted rail travel in Exeter. This account, if accurate, would represent the earliest known instance of space weather affecting technology.
Typo Identified in Historical Record
A paper published in the journal Space Weather indicates that the 1841 date is likely a typographical error. The actual railway disruption is believed to have occurred several years later, adjusting the historical timeline for such events.
Historical Context of Space Weather Impacts
Co-author Jim Wild of Lancaster University noted that this study demonstrates society has experienced the effects of space weather on technology for nearly as long as electrical technologies have existed. The Exeter train delay highlights an early interaction between emerging technologies and the space environment.
The Carrington Event Remains Most Powerful
The 1859 Carrington Event continues to be the most powerful geomagnetic storm on scientific record. This event caused widespread auroral displays, sparking in telegraph stations, and fires. Telegraph systems, a relatively new technology at the time, were significantly affected by geomagnetically induced currents, with some operators able to transmit messages using only the auroral current after disconnecting power supplies.

Reporting from
A new paper suggests an 1841 report of space weather disrupting rail travel in Exeter was likely a typo, with the actual event occurring later. This research clarifies the historical timeline of space weather impacts on early electrical technologies, predating the 1859 Carrington Event.
