Giant sunspots visible from EarthBoulder, Colo. (UPI) May 9, 2012 Giant sunspots have sent clouds of particles toward Earth that could bring northern auroras but aren't expected to disrupt communications, U.S. scientists said. A large group of sunspots headed toward Earth during the weekend and two coronal mass ejections erupted from the Sun's surface Tuesday, they said. The ejection could arrive on Earth late Wednesday and cause moderate geomagnetic storms and auroras in the higher altitudes, the National Oceanographic and Atmospheric Administration's ... read more |
