> GEOMAGNETIC STORM WARNING: One and perhaps two CMEs are about to hit Earth. The first, hurled toward us by last Thursday's solar tsumani (C3), is expected to arrive on Aug.30.

> Currently, AR2860 is crackling with minor C-class solar flares. However, it has a "beta-gamma" magnetic field that harbors energy for stronger M-classeruptions. Solar flare alerts: SMS Text.
