今明两天！北方多地或出现极光

Group 1 - The National Space Weather Monitoring and Warning Center of China Meteorological Administration predicts moderate geomagnetic activity in the next two days [1][3] - Northern regions of China, such as Mohe in Heilongjiang, Xinjiang, and Inner Mongolia, may witness auroras tonight to early tomorrow morning, primarily featuring weak red auroras with a small chance of red-green composite auroras [1] - Public interested in viewing the auroras should look for clear skies and low light pollution areas [1] Group 2 - The occurrence of auroras is linked to solar activities such as solar flares and coronal mass ejections, which release high-speed charged particle streams [2] - These particles interact with the Earth's magnetic field, leading to geomagnetic activity and resulting in the beautiful display of auroras when they collide with atmospheric gas atoms [2]
