Researchers say an alleged 1841 geomagnetic disruption to UK railways was likely a typo, revising early space weather history

A study in Space Weather reexamines an 1871 Nature report claiming a magnetic storm disrupted rail travel in Exeter in October 1841. The researchers conclude the date was likely a typo and the incident occurred several years later, meaning it may not predate other early reports of space weather affecting technology.

The finding narrows the historical timeline for when electrical infrastructure first showed vulnerability to solar storms. It also underscores that risks to modern grids, satellites, and communications are part of a much longer pattern of technology exposure to the space environment.
