Summary:
- Researchers utilized historical train logs from the 19th century to pinpoint the exact timing and intensity of a major solar storm that occurred in 1859, known as the Carrington Event.
- By analyzing telegraph logs recorded during train operations, scientists were able to map the storm's impact on Earth's geomagnetic field with greater precision than previously possible.
- This study demonstrates how interdisciplinary approaches, combining archival historical data with modern space physics, can improve our understanding of historical space weather events and their potential risks to modern infrastructure.
