A powerful solar storm produces stunning auroras

An intense solar storm has the northern lights gracing the skies farther south than usual.A blast of superhot material from the sun late last week hurled scorching gases known as plasma toward Earth at nearly 2 million mph (3 million kph), the National Oceanic and Atmospheric Administration said Monday.
Earth felt the brunt of the storm Sunday, according to NOAA, with forecasters warning operators of power plants and spacecraft of the potential for disruption.Auroras were reported across parts of Europe and Asia. In the U.S., skygazers took in the sights from Wisconsin, Washington state, Colorado, California, New Mexico and even Arizona — mostly a reddish glow instead of the typical green shimmer.
“I don’t want any expectations of these green curtains moving back and forth” so far south, said Bill Murtagh, program coordinator at the NOAA Space Weather Prediction Center in Boulder, Colorado.
Although conditions have eased, auroras might still be visible as far south as South Dakota and Iowa late Monday and early Tuesday if skies are dark.The farther north, the better the show as the energized particles interact with the atmosphere closer to Earth, according to Murtagh.
