Aurora forecast

The map shows where and how strongly the aurora is expected to be visible in the next 30 to 90 minutes.

Tonight’s Aurora forecast over USA

tonights aurora forecast Tonight’s aurora forecast over the USA from NOAA shows a predicted map of where the northern lights may be visible across North America, with a “viewline” marking the southernmost areas from which you could see the aurora on the northern horizon based on the expected geomagnetic activity tonight (6 pm to 6 am Central Time). The forecast uses colors and contours to estimate the intensity and location of the aurora around the magnetic pole, and if the predicted activity is strong enough, auroras could be seen well into the northern United States after dark, though darkness and clear skies are still needed for viewing.

What is Aurora

Aurora, also called the Northern Lights, is a natural light display in the sky caused by charged particles from the Sun hitting Earth’s magnetic field and atmosphere. These particles collide with gases high above the Earth, creating glowing colors such as green, pink, red, and purple. Auroras are most often seen near the North Pole during dark, clear nights and become stronger when solar activity is high.

Increased solar activity

In recent years, increased solar activity has pushed the aurora farther south than usual, making the Northern Lights visible not only near the Arctic but also across parts of the USA, Europe, and Asia.

What Aurora map shows

aurora forecast next 30 minutes This map shows where the northern lights are likely to appear in the next 30 to 90 minutes. It is based on real-time space weather data collected by satellites and processed by NOAA, the U.S. space weather agency.

Focus on the northern hemisphere

The map uses a polar view of the Northern Hemisphere, centered on the North Pole. This makes it easy to see how far south the aurora may reach and which regions have a chance to see it.

Color meaning and aurora strength

Colors on the map show how strong the aurora is expected to be. Green areas mean a lower chance of visible aurora, while yellow and red areas show stronger activity and a higher chance of bright auroras in the sky.

Aurora oval shape

The colored band forms an oval shape around the pole, called the auroral oval. When space weather is calm, this oval stays close to the pole. When activity increases, it grows and moves farther south.
