"Northern Lights Expected to Illuminate Northeastern US This Weekend"

The northern lights, also known as the aurora borealis, are expected to be visible across northern New England on Saturday night, with a possibility of being seen in Massachusetts and even as far south as Washington, D.C. Clear skies and a sliver of a crescent moon make for ideal viewing conditions. The northern lights occur when solar energy from the sun collides with Earth's magnetic field, creating waves of color.
