Aurora borealis forecast tonight: Northern lights visible in these 15 states. Can you brave winter weather for a geomagnetic storm?

The Northern Lights, also known as aurora borealis, may be visible in more than a dozen U.S. states Tuesday, December 9, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (NOAA).

A full-halo coronal mass ejection (CME) is expected to reach Earth early to midday on Tuesday, potentially causing periods of “strong” G3 geomagnetic storms (on a scale of G1 to G5).

The aurora borealis is the result of a geomagnetic storm that occurs when a coronal mass ejection (CME), an eruption of solar material, reaches Earth and causes swaths of purple, blue, and green in the night sky. This year’s increased solar activity (and thus, more frequent northern lights activity) is likely the result of an 11-year sun cycle peak.

Here’s what to know about how to see the spectacular view.

Where will the northern lights be visible?

The aurora “may be visible over a number of northern U.S. states and lower Midwest to Oregon” on Tuesday, per the NOAA’s alert.

According to the NOAA’s map, a total of 15 states are in the line of view for the aurora tonight. Those states include: Alaska, Washington, Oregon, Idaho, Montana, Wyoming, North Dakota, South Dakota, Minnesota, Iowa, Wisconsin, Michigan, New York, Vermont, and Maine.

When is the best time to see the aurora borealis?

For the best viewing, the NOAA recommends facing north, in a spot away from light pollution, between 10 p.m. and 2 a.m. local time.

You can track the aurora on the NOAA’s website, where the agency is providing updates and visibility in real time, with a 30-minute aurora forecast.
