Ferocious solar storm could give US rare view of northern lights

Large sunspot cluster has produced several moderate to strong solar flares since Wednesday morning, Noaa says

A ferocious solar storm powerful enough to knock out or disrupt satellite and communications systems, the power grid and radio signals was raging Friday, space weather researchers warned.

The severity of the geomagnetic storm that has propelled multiple solar flares towards Earth in recent days also brings a spectacular bonus for sky watchers: a rare but stunning view of the aurora borealis, otherwise known as the northern lights, in places they are rarely seen in the US.
