Geomagnetic Storm to Brighten Northern Lights in 18 States

Tonight, the northernmost states are expected to witness a spectacular display of the northern lights, with the National Oceanic and Atmospheric Administration (NOAA) predicting an unusually vibrant aurora borealis, triggered by a potent geomagnetic storm. This surge in solar activity is set to produce an aurora that may be brighter and more active than usual, offering an extraordinary opportunity for stargazers and photographers alike. According to NOAA’s three-day aurora borealis forecast, Monday night’s aurora could feature a Kp index as high as 6.67, on a scale of 0 to 9. A Kp index of 6 or higher indicates a very strong aurora, meaning the lights could be visible even from areas that don’t normally see them. This heightened activity is the result of a strong G3-level geomagnetic storm expected to unfold overnight. The storm was triggered by an ejection of solar material from the sun on Sunday, which has since collided with Earth’s magnetic field.

The northern lights are expected to be visible from 18 states, but Alaska stands out as the prime location for the best views. Residents and visitors in Alaska have the highest chance of experiencing this bright and active aurora borealis display. NOAA’s forecast suggests that the geomagnetic storm’s effects will be strongest in the northern parts of the U.S., but the display could extend as far south as states like Washington, Idaho, and Montana. In addition to Alaska, other states with a relatively high likelihood of witnessing the northern lights include North Dakota, South Dakota, Minnesota, Michigan, and Wisconsin. For those living further south, there is still a chance to view the aurora, particularly along the line marking its southernmost visibility. States such as Oregon, Wyoming, Nebraska, Iowa, Illinois, New York, Vermont, New Hampshire, and Maine could see the aurora’s southern boundary, though the display may not be as intense in these locations.

For those eager to catch a glimpse of the northern lights, NOAA advises stargazers to venture outdoors between 10 p.m. and 2 a.m. local time, when the aurora will be at its peak. This period is generally the most favorable for observing the lights, as the geomagnetic storm will be fully underway. The agency also recommends finding a high vantage point, such as a hill or mountaintop, to avoid obstructions and maximize the viewing experience. Light pollution can interfere with the visibility of the aurora, so heading to a location far from city lights is crucial. In addition to heading north and finding a clear viewing spot, it’s important to dress warmly. Aurora hunting can take place in some of the coldest parts of the country, especially in Alaska and northern states. Staying comfortable while waiting for the lights to appear will ensure a better viewing experience.

For those looking to photograph the breathtaking aurora, National Geographic offers valuable tips. A tripod is essential for keeping the camera steady during long exposure shots, which are necessary to capture the full beauty of the northern lights. Using a wide-angle lens allows for a broader view of the night sky, while a low shutter speed will help capture the movement of the aurora. Night mode on smartphones, such as the iPhone, can also yield impressive results, but a tripod remains key for stability. The northern lights’ dramatic display is not just a feast for the eyes but a mesmerizing subject for photography. The colors and shapes of the aurora, ranging from greens to purples, can appear dynamic and ethereal, making for photos that capture the wonder of the natural world.

The northern lights are visible during periods of heightened solar activity, and this year, solar activity has exceeded expectations. According to NASA, the sun has reached its “solar maximum” as part of its 11-year solar cycle, resulting in a surge of solar flares, geomagnetic storms, and coronal mass ejections. This solar maximum phase began to intensify in 2023 and is expected to continue into 2025 and 2026. During this period of heightened solar activity, the aurora borealis is more likely to appear at latitudes where it’s typically harder to catch a glimpse of the lights. In fact, the visibility of the northern lights has hit a 500-year peak this year, a phenomenon that has been linked to the current solar maximum. As the sun continues to exhibit high levels of activity, scientists predict that geomagnetic storms and other solar events will remain common, contributing to more frequent and intense displays of the aurora borealis.

For those who may not be able to witness tonight’s aurora, there is still good news. NOAA’s forecast predicts that the geomagnetic storm will continue into Tuesday night, with a slightly lower but still strong Kp index of 5. This means that while the aurora’s intensity may decrease slightly, the lights will still be visible across the same general regions, including Alaska and parts of the northern U.S. If you miss out on Monday night’s show, there will be additional opportunities throughout the coming weeks as solar activity remains elevated. NASA’s predictions suggest that the aurora will continue to put on an impressive display well into the next couple of years, with the best opportunities to view it in northern latitudes.

The northern lights forecast for tonight offers an exciting chance to witness one of nature’s most spectacular phenomena. With a strong geomagnetic storm in progress, the aurora borealis will be brighter and more active than usual, visible across 18 states, including Alaska and parts of the northern U.S. To maximize the experience, viewers should head outdoors between 10 p.m. and 2 a.m., find a high vantage point, and escape light pollution. For photographers, using a tripod, a wide-angle lens, and a long exposure setting will help capture the beauty of the aurora. With heightened solar activity in the coming years, there will be more opportunities to experience this breathtaking light show.
