G2-CLASS GEOMAGNETIC STORM: A moderately strong G2-class geomagnetic storm is underway on May 27-28 as Earth moves through the wake of a CME that swept past our planet just hours ago. High-latitude sky watchers should be alert for auroras, especially in the southern hemisphere where deepening autumn darkness favors visibility.
