Mysterious Aurora Over Japan: Is This Proof of Much Stronger Space Storms?
A faint red aurora over Japan could be evidence of space storms much stronger than previously thought.
TL;DR
- Faint red auroras observed over Japan are extending to higher altitudes (500-800 km) than previously thought.
- These auroras are appearing during storms classified as moderate, challenging current understanding of space storm formation.
- The intense compression of Earth's magnetosphere during these events suggests the storms might be stronger than standard measurements show.
- This phenomenon can lead to increased atmospheric drag on satellites, potentially affecting their orbits.
- Citizen scientists played a crucial role in gathering data through widespread observation across Japan.
- Improved understanding of these events is vital for more accurate space weather forecasting and safer satellite operations.
