"Rare Northern Lights Display Expected to Illuminate Northeastern US This Weekend"

The northern lights, also known as the aurora borealis, may be visible in northern Massachusetts, as well as other parts of New England, on Saturday night. The Space Weather Prediction Center of the National Oceanic and Atmospheric Administration has forecasted the appearance of the aurora. To best see the phenomenon, viewers should find a location with an unobstructed view towards the north or south, away from city lights and the full moon. The best time to observe the aurora is usually within an hour or two of midnight. The aurora is caused by the interaction of the solar wind with Earth's magnetic field, resulting in the production of light when electrons collide with atoms and molecules in the upper atmosphere.
