The Sun viewed on 29 January 2025 in the extreme ultraviolet range by NASA's Solar Dynamics Observatory (SDO) spacecraft. A vast 500,000 mile-wide coronal hole has opened in the sun's atmosphere. The area measures over 62 times the diameter of Earth and is now shooting high-speed solar wind toward Earth. When such solar activity is directed at Earth, the resulting geomagnetic storms can potentially disrupt satellite operations, power grids, navigation systems, and radio communications. There may also be spectacular displays of aurora caused as the Earth's magnetosphere is disturbed by the solar wind. According to spaceweather.com, this wind is estimated to hit Earth by Friday (31 Jan), resulting in G1 geomagnetic storm conditions.
