Space weather caused a 16-minute train delay in 1848: ‘Our research has a hint of a detective story’

AI-summarised brief · reviewed before publication

A team led by Professor Jim Wild re‑examined a 19th‑century train delay that had been cited as the first solar‑storm disruption of technology. By cross‑checking railway timetables, newspapers, and geomagnetic records, they found the Exeter train incident actually occurred on 18 October 1848, not 1841, and that the earliest recorded electrical disturbance was a 1847 Midland Railway event. The study underscores how early electrical infrastructure was vulnerable to space weather and demonstrates the value of archival research in reconstructing historic geomagnetic storms.
