GEOMAGNETIC STORM UNDERWAY NOW: A surprise geomagnetic storm is underway on May 14th. Storm levels are currently at G3 (strong), which means auroras may be visible as low as Illinois and Oregon (typically 50° geomagnetic lat.) The Solar Wind Speed is above 550 km/s. The reason for the storm is a crack that has opened in Earth's magnetic field, allowing solar wind to enter the magnetosphere. MULTIPLE CMEs ARE COMING: Three and possibly four CMEs are en route to Earth following a series of explosions near sunspot AR2741. The most potent so far occurred on May 12th when a filament of magnetism surrounding the sunspot became unstable and erupted. The blast zone was more than 200,000 km in diameter.
