Episode notes
Northern Lights Origin
- The Northern Lights, or Aurora Borealis, originate from the sun's solar wind.
- This wind interacts with Earth's magnetic field, causing charged particles to excite atmospheric gases and emit light.
Auroral Movement
- The dance-like movements of the aurora are caused by magnetic stress within Earth's magnetosphere.
- Magnetospheric substorms create short bursts of dynamic auroral activity.
Aurora Forecasting
- Aurora forecasting involves analyzing solar activity, solar wind properties, and ground-based magnetometer readings.
- It's a three-stage process with increasing confidence as the event approaches.
