Solar storms brought colorful auroras to unexpected places and there could be more to come. Space weather forecasters confirmed that storms reached severe levels Tuesday night, triggering northern lights in Europe and as far south as Kansas and Texas in the U.S. There were some impacts to GPS communications and the power grid. Over the past few days, the sun has burped out several bursts of energy called coronal mass ejections. Two have reached Earth, but at least one more is still on the way. The sun is at the maximum phase of its 11-year activity cycle, making auroras more common and widespread.
