CAPE CANAVERAL, Fla. (AP) — An unusually strong solar storm hitting Earth produced stunning displays of color in the skies across the Northern Hemisphere early Saturday, with no immediate reports of disruptions to power and communications.

The U.S. National Oceanic and Atmospheric Administration issued a rare severe geomagnetic storm warning when a solar outburst reached Earth on Friday afternoon, hours sooner than anticipated. The effects of the Northern Lights, which were prominently on display in Britain, were due to last through the weekend and possibly into next week.
