Episode notes
The Carrington Event
- In 1859, Richard Carrington saw a flash near a sunspot, followed by a huge aurora seen as far south as Cuba.
- Telegraph machines sparked, shocking operators and even operating while unplugged.
Sun-Aurora Connection
- The Carrington Event revealed the connection between solar activity and auroras.
- Carrington's observation linked the solar flare he witnessed to the widespread aurora displays.
Solar Flares and CMEs
- Solar flares are sudden releases of energy and particles from the sun, and CMEs eject hot plasma into space.
- While flares primarily release radiation, CMEs send chunks of the sun towards Earth at incredible speeds.
