#CME IMPACT SPARKS GEOMAGNETIC STORM: Geomagnetic storms are underway following the arrival of a CME on Aug. 27th. At first, the CME's impact appeared weak and, indeed, it did not cause an immediate geomagnetic storm. Since then, however, magnetic fields in the CME's wake have linked to Earth's magnetic field, causing storms of category G2 (with a chance of G3) on Aug. 28th. CME impact alerts: SMS Text

"What a year, so many auroras from central Europe have not been visible since 2001!" he says.
