Red Aurora Over Japan Signals Potentially Powerful Solar Storms
Scientists have observed an unusual red aurora over Japan, suggesting that some solar storms may be more powerful than previously thought. The aurora, recorded in June 2024, reached altitudes between 500 to 800 kilometers, higher than typical for moderate storms. This phenomenon indicates that even moderate geomagnetic storms can contain significant energy. The study, led by Tomohiro Nakayama, highlights the rarity of auroras in Japan due to its southern location. The red aurora was attributed to a dense solar wind interacting with Earth's magnetic field. The research, published in the Journal of Space Weather and Space Climate, aims to improve predictions of space weather that could impact satellites and power grids.
