The Northern Lights continue to dazzle viewers across the northern United States and Canada.

It has been a good year for seeing the northern lights, even in the lowest regions. This is due to increased electromagnetic activity as the sun approaches the peak of its 11-year solar cycle.

The National Oceanic and Atmospheric Administration (NOAA) says that if skies are clear, the phenomenon could be visible in parts of the northern United States Wednesday night, including Washington, Idaho, Montana, the Dakotas, Minnesota, Wisconsin, Michigan and Maine.

Increased solar activity can also interfere with radio transmissions on Earth.

NOAA advises those hoping to see the northern lights to head away from city lights. The best time to see them is typically an hour or two before or after midnight. The agency says the best times are during the spring and fall equinoxes, due to how the solar wind interacts with Earth’s magnetosphere.
