Solar radiation from a massive sun storm -- the largest in nearly a decade -- collided with the Earth's atmosphere on Tuesday, prompting an airline to reroute flights and skywatchers to seek out spectacular light displays.
US carrier Delta Air Lines said it had adjusted flight routes for transpolar journeys between Asia and the United States to avoid problems caused by the radiation storm, a spokesman said.
NASA confirmed the coronal mass ejection (CME) began colliding with Earth's magnetic field around 10:00 AM (1500 GMT) Tuesday, adding that the storm was now being considered the largest since October 2003.
