Northern Lights in 2025: How Solar Activity is Bringing the Aurora Borealis Closer to the U.S.
Solar storm impact: In 2025, the Northern Lights, or aurora borealis, are expected to be more visible across parts of the U.S., thanks to heightened solar activity. This is due to the sun being at the peak of its 11-year solar cycle, a phase that significantly increases the frequency of solar storms.
These storms occur when the sun expels bursts of plasma, called coronal mass ejections (CMEs), into space. When these CMEs reach Earth, they interact with the planet’s magnetic field, causing geomagnetic storms. These storms often result in the spectacular light displays known as the Northern Lights.
The latest forecast from NOAA suggests that the solar activity this winter could lead to geomagnetic storms strong enough to make the auroras visible in states as far south as Oregon and New York.
Areas such as Alaska, North Dakota, Montana, and parts of New England are expected to have the best chance of viewing these colorful light shows. Experts predict that clear, dark skies away from city lights will offer the best viewing conditions.
Solar cycles affect the frequency of auroras, with increased solar activity leading to more vibrant and frequent displays. While predicting the exact timing of these events remains challenging, scientists track solar storms through instruments like NOAA’s DSCOVR and NASA’s ACE spacecraft.
These tools help forecast the arrival of solar bursts, providing skywatchers with a window of opportunity to witness the stunning effects of solar activity on Earth’s atmosphere. As solar activity continues into 2025, sky enthusiasts can look forward to a more frequent and dazzling aurora season.
The Science Behind Geomagnetic Storms: What Causes the Northern Lights?
Geomagnetic storms, responsible for the Northern Lights, are caused by disturbances in Earth’s magnetic field, triggered by solar activity. The sun’s surface continuously releases charged particles through solar winds, but during periods of heightened activity, it expels bursts of plasma known as coronal mass ejections (CMEs).
These CMEs carry vast amounts of solar material and magnetic fields, which can travel through space and impact Earth’s magnetosphere, the protective shield around our planet.
When a CME collides with the Earth’s magnetosphere, it compresses the magnetic field, creating a disturbance that energizes particles in the atmosphere, primarily electrons and protons. As these energized particles interact with gases like oxygen and nitrogen in the Earth’s upper atmosphere, they produce light—a phenomenon known as the aurora borealis, or Northern Lights.
The colors of the aurora, typically green, red, and purple, depending on the type of gas and the altitude at which the particles collide. But skywatchers in some areas may get a second night to see the aurora borealis on Jan. 1.
The intensity of geomagnetic storms is measured on a scale from 1 to 5, with higher levels indicating stronger storms. During stronger storms, auroras can be seen further south, providing a rare spectacle for viewers in areas not typically associated with auroras, like parts of the U.S.
During the sun’s 11-year solar cycle, these storms become more frequent and intense, reaching their peak during solar maximum, which is happening now. Solar activity is expected to continue affecting Earth through 2025, making geomagnetic storms—and the resulting Northern Lights—more common.
In essence, geomagnetic storms are a fascinating result of solar interactions with Earth’s magnetic field, creating one of nature’s most beautiful and mysterious phenomena.

Where to See the Northern Lights in the U.S. This New Year’s: A Skywatcher’s Guide
As the New Year approaches, skywatchers in the U.S. have a chance to witness the Northern Lights, thanks to heightened solar activity. Due to the sun being at the peak of its 11-year cycle, solar storms are expected to increase, making the aurora borealis visible in areas farther south than usual. The key to spotting the Northern Lights is finding clear, dark skies, ideally away from city lights.
The best viewing locations for the Northern Lights in the U.S. include states like Alaska, which is consistently one of the best places to see the aurora. However, thanks to the strength of upcoming solar storms, other northern states may also have opportunities. Look for auroras in places like Montana, North Dakota, Minnesota, Wisconsin, Michigan, New Hampshire, Vermont, and Maine. These regions are expected to have the best chances of seeing the aurora borealis, especially during the early morning hours when the light display is most active.
Additionally, parts of Oregon, Idaho, Wyoming, Iowa, and New York could also experience brief views of the aurora, depending on the intensity of the solar storms. The Northern Lights are typically visible in areas closer to the Arctic Circle, but during strong geomagnetic storms, their reach extends further south, providing a rare treat for those in more southern latitudes.
For the best viewing experience, it’s important to check the weather for clear skies and go to a location with minimal light pollution. If you have a smartphone, it can also help capture details of the aurora that might not be visible to the naked eye. With the current solar activity, this New Year’s could be a prime time for witnessing this spectacular natural light show across much of the U.S.
How Solar Cycles Affect the Frequency of the Northern Lights: What You Need to Know
The Northern Lights, or aurora borealis, are directly influenced by the sun’s 11-year solar cycle, a period during which the sun’s activity waxes and wanes. This cycle involves variations in the number of sunspots, solar flares, and coronal mass ejections (CMEs), which all impact the Earth’s magnetic field and the visibility of auroras.
During periods of high solar activity, known as solar maximum, the sun releases more solar material and charged particles, increasing the chances of geomagnetic storms that produce spectacular auroras.
As the sun moves toward the peak of its cycle, solar flares, and CMEs become more frequent and intense. These solar eruptions send bursts of charged particles toward Earth, where they interact with the planet’s magnetosphere, creating the stunning light displays known as the Northern Lights. The stronger the solar activity, the more vibrant and widespread the auroras can be, often reaching latitudes further south than usual.
The solar cycle is predictable, but its exact timing and intensity are difficult to forecast. Scientists monitor solar conditions through satellites and instruments that track solar wind and solar flares. Currently, we are in an active phase of the solar cycle, with solar activity expected to peak around 2025. This means that the frequency of auroras will increase over the next few years, providing more opportunities for people in the U.S. and other northern regions to witness the Northern Lights.
Understanding the solar cycle helps predict when and where auroras are most likely to occur. With the peak of the solar cycle on the horizon, the next few years will offer an exciting opportunity for skywatchers to experience the awe-inspiring beauty of the Northern Lights more frequently.
Solar storm impact: What It Means for Earth and Our Technology
Solar storms, particularly powerful geomagnetic events, can have significant impacts on both Earth’s natural phenomena and our technological systems. These storms, driven by the sun’s release of coronal mass ejections (CMEs) and solar flares, can disrupt communications, GPS systems, power grids, and satellite operations. As solar activity increases with the sun nearing the peak of its 11-year cycle, the potential for strong solar storms also rises, making it essential to prepare for their effects.
Solar storms occur when CMEs, streams of charged particles, collide with Earth’s magnetic field, creating geomagnetic disturbances. While these interactions produce the beautiful Northern Lights, they can also interfere with high-frequency radio communications, which are crucial for aviation, maritime operations, and military activities. Solar storms can also cause GPS inaccuracies and affect satellite functions, leading to disruptions in navigation and weather forecasting.
One of the most concerning potential impacts is on power grids. Strong geomagnetic storms have the ability to induce electrical currents in power lines, which could damage transformers and other critical components, leading to widespread blackouts. While such severe storms are rare, their potential damage is significant, making it important for utilities and governments to take preventive measures.
Monitoring solar activity is key to mitigating the risks of solar storms. NOAA and other space agencies track solar eruptions using satellites and other instruments, providing early warnings to help protect technology. As solar storms become more frequent during this period of heightened solar activity, both individuals and industries must be prepared for potential disruptions while continuing to enjoy the awe-inspiring spectacle of the Northern Lights. Understanding and preparing for solar storms ensures that we can balance the beauty of space weather with the resilience of our technological infrastructure.
