You may get the chance to see the northern lights tonight, June 25, as the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center predicts a geomagnetic storm, which produces the famous purple, pink and green lights that dance across the sky.
NOAA is forecasting a G2-level geomagnetic storm – classified as moderate – with the agency’s Kp index forecast to peak at 5.67. The level of activity is strong enough to generate auroras visible as far south as parts of the northern United States.
Aurora visibility across 14 states
NOAA’s map to view the aurora shows that the displays may be visible across 14 U.S. states: Alaska, Minnesota, North Dakota, Montana, Maine, Michigan, Wisconsin, Vermont, New Hampshire, Washington, Oregon, Idaho, New York and South Dakota.
According to Space.com, Alaska has the highest chance of seeing a vivid display tonight, though other areas not listed may also catch a glimpse if local weather and geomagnetic conditions align.
What causes the northern lights?
The northern lights, known as the auroras borealis, occur when the sun emits bursts of charged particles that collide with gases like oxygen and nitrogen in Earth’s upper atmosphere. These collisions release energy in the form of colorful light displays.
Typically, auroras are most visible near the magnetic poles, in places like Alaska, Canada or northern Europe. However, during periods of heightened solar activity, these light shows can extend farther south into regions that typically don’t see them.
When and where to watch
For the best chance at spotting the aurora tonight, head to a dark area away from city lights with a clear view of the northern horizon. The Geophysical Institute of the University of Alaska Fairbanks says the ideal viewing window is from late evening to early morning under clear skies.
