Scientists correct 155-year-old solar storm mix-up: Train delay was in 184

Researchers have corrected a 155-year-old historical error regarding the timing of a solar storm-related train delay in Exeter. By cross-referencing contemporary newspaper reports with archival railway records, scientists determined that the incident occurred on October 18, 1848, rather than the date previously attributed to the event.

This finding clarifies a long-standing discrepancy in the historical record of solar activity. The verification process highlights the importance of using primary source documentation to accurately map the timeline of historical geomagnetic disturbances.
