New video shows stunning Aurora Borealis over South Dakota

Last week's severe geomagnetic storm created Aurora Borealis light shows like this one in South Dakota along with others that were visible as far south as Florida.

This week's forecast calls for a return to relatively quiet geomagnetic activity. However, according to Nasa, the sun is currently at the peak of its 11-year cycle, known as "solar maximum", which could lead to more, severe geomagnetic storms.
