- A rare red aurora was observed over Hanle, Ladakh, after a powerful solar flare triggered a geomagnetic storm.
- The event followed an X-class solar flare, the strongest type of solar eruption.
- The flare produced a Coronal Mass Ejection (CME) that struck Earth’s magnetosphere, causing a G4-level geomagnetic storm (severe).
- The red aurora occurred due to excited oxygen atoms at very high altitudes (above 300 km).
- Data from the Aditya-L1 mission showed strong compression of Earth’s magnetosphere during the storm.
- Solar radiation storms can disrupt satellites, GPS, communication systems, and power grids.
