Northern Lights Forecast: Aurora Borealis Expected In These 10 States Tonight

Forbes - Apr 22nd, 2025

The northern lights, also known as the aurora borealis, are expected to be visible in several U.S. states along the Canadian border on Tuesday night, following a series of geomagnetic storms. According to the National Oceanic and Atmospheric Administration (NOAA), auroral activity is forecasted with a Kp index of four on a scale of nine, meaning the lights could be visible in as many as 10 states. While no geomagnetic storm conditions are anticipated on Tuesday, similar auroral activity is predicted for Wednesday and Thursday. Northern Alaska and Canada have the highest chance of visibility, but parts of northeastern Washington, northern Idaho, Montana, North Dakota, Minnesota, and Upper Michigan may also catch a glimpse.

This opportunity comes amid a peak period of northern lights displays, which began in October 2024 due to heightened solar activity. NASA and NOAA have attributed this peak to a "solar maximum"—a period marked by an increase in solar flares and coronal mass ejections. These events excite electrons that interact with Earth's atmospheric molecules, resulting in the vibrant displays of the aurora borealis. This phase is expected to continue into early 2026, offering more chances to witness this natural spectacle. The strongest geomagnetic storm in two decades, which occurred in May 2024, extended the reach of the northern lights as far south as northern Florida and Texas, underscoring the ongoing intensity of solar activity.

Fair Story

Consider it well-founded

The article provides a well-rounded and informative overview of the northern lights' visibility in the U.S., supported by reputable sources like NOAA and NASA. It excels in clarity and readability, offering practical advice for viewers. However, it could improve by enhancing transparency with direct data links and expanding its source variety to include local perspectives. While its impact is primarily educational and engaging for enthusiasts, it lacks elements that might provoke broader societal debate. Overall, the article effectively informs readers about a captivating natural phenomenon, maintaining accuracy and balance throughout.

Accuracy

The article provides a generally accurate depiction of auroral activity and its visibility across certain U.S. states. The claim about auroral activity with a Kp index of four is consistent with NOAA's projections, suggesting the northern lights could indeed be visible in several northern states. However, the article could enhance its accuracy by specifying the exact states and comparing them with NOAA's real-time data. The historical context about the solar maximum and the strongest geomagnetic storm in May 2024 is accurate and aligns with NASA's and NOAA's reports. While the geographical scope of visibility is plausible, the article could improve by referencing specific NOAA maps or data to support these claims.

Balance

The article maintains a neutral tone, focusing on the scientific aspects of auroral activity without delving into speculative or anecdotal evidence. It balances its content by providing both the scientific explanation and practical viewing advice. However, it could increase balance by including perspectives from additional sources, such as local weather experts or astronomers, to provide a more comprehensive view of the aurora's impact on different communities.

Clarity

The article is well-structured and clear, with a logical flow from the forecast to practical viewing tips. It uses straightforward language that is accessible to a general audience, explaining technical terms like the Kp index in a comprehensible manner. The inclusion of practical advice, such as optimal viewing times and photography tips, enhances clarity by providing actionable information for readers.

Source quality

The article primarily relies on reputable sources such as NOAA and NASA, which are authoritative in the field of space weather and auroral activity. These organizations provide reliable data and forecasts, lending credibility to the article. However, the article could improve source quality by directly citing these organizations' latest reports or data, ensuring that readers can verify the information independently.

Transparency

The article is somewhat transparent in its methodology, mentioning NOAA's forecasts and the Kp index. However, it lacks detailed explanations of how these forecasts are derived or the limitations of these predictions. The article does not disclose any conflicts of interest, which suggests an unbiased presentation, but it could enhance transparency by linking directly to the data sources or providing more context on the scientific processes involved.
