Episode notes
Carrington's Firsthand Solar Flare Observation
- Richard C. Carrington observed intensely bright white flashes on a large sunspot group on September 1st 1859, later tied to the global magnetic storm.
- He sketched the spots, timed the flash, and noted magnetometer disturbances about 17 hours later.
How 1859 Linked Sunspots To Global Magnetic Storms
- The Carrington Event was a massive 1859 geomagnetic storm that produced auroras seen far from the poles and triggered global magnetic disturbances.
- Observatories, sunspot records, and telegraph networks already in place let scientists correlate a solar flare with Earth effects.
Auroras Reached Tropics During The Storm
- The event produced auroras seen as far south as Cuba, Panama, Hawaii and Key Largo and in the southern hemisphere across Tasmania and Australia.
- Two main waves on Aug 28–29 and Sept 1–2 expanded the visible auroral zone well beyond normal latitudes.
