7,000 Kilometer Gravity Anomaly And “Geomagnetic Jerk” Detected By NASA Over The Atlantic

Researchers looking through data from NASA and the German Aerospace Center (DLR)’s Gravity Recovery and Climate Experiment (GRACE) have found an odd gravity anomaly over the Atlantic Ocean. Attempting to find the cause of the anomaly, the team found it may be associated with a “geomagnetic jerk” detected around the world. There is still plenty to learn about the Earth’s …

Aurora alert! Butterfly-shaped ‘hole’ in sun’s atmosphere could spark geomagnetic storm Sept. 13-14

A colossal butterfly-shaped coronal hole has opened in the sun’s atmosphere and is currently spewing a fast-moving stream of solar wind toward Earth that could trigger a moderate geomagnetic storm and dazzling auroras this weekend. The high-speed solar wind from this striking feature, spanning some 310,000 miles (500,000 kilometers) across, is expected to reach Earth around Sept. 14. Space weather …
