Washington, D.C. — Skywatchers across North America may soon get another chance to witness the breathtaking northern lights as scientists closely monitor a massive sunspot region rotating toward Earth.
The growing solar activity has sparked excitement among astronomers and aurora enthusiasts alike, especially after reports of powerful solar flares erupting from the giant sunspot area in recent days.
Massive Sunspot Region Raises Aurora Hopes
According to scientists, one of the largest sunspot regions seen in years was recently detected on the far side of the sun by the European Space Agency’s Solar Orbiter spacecraft.
Because the sun rotates approximately every 27 days, regions previously hidden eventually rotate into Earth’s view. Researchers are now closely watching the enormous sunspot as it gradually turns toward the planet between Friday, May 22, and the following several days.
The excitement surrounding the event comes from the fact that sunspots are capable of producing powerful solar eruptions that can directly affect Earth’s magnetic field.
Solar Flares Could Trigger Geomagnetic Storms
NASA says sunspots are highly magnetic regions that can unleash intense solar flares and coronal mass ejections, commonly known as CMEs.
These eruptions release massive clouds of charged particles into space. When those particles collide with Earth’s atmosphere, they can trigger geomagnetic storms that create the colorful waves of light known as the aurora borealis, or northern lights.

Reports indicate the sunspot region already produced two X1-class solar flares along with more than a dozen M-class flares between Friday, May 15, and Saturday, May 16.
Scientists say additional eruptions could rapidly increase aurora activity if future CMEs head toward Earth.
When Could the Northern Lights Be Visible?
At the moment, no major geomagnetic storm warning has been officially issued. However, experts say conditions could change quickly depending on solar activity in the coming days.
If stronger geomagnetic storms develop, the best opportunity to view the northern lights will likely occur during the darkest overnight hours.
Experts recommend watching the skies between 10 p.m. and 2 a.m. local time, especially in areas with clear weather and minimal artificial light.
The aurora can sometimes appear faint to the naked eye at first, often resembling glowing white or green streaks before becoming more vivid as activity intensifies.
Where Could the Aurora Be Seen?
If solar activity strengthens enough, the northern lights could become visible across parts of Canada and the northern United States, particularly states located closer to the Canadian border.
During especially powerful geomagnetic storms, the aurora can sometimes stretch much farther south than usual, surprising residents in areas that rarely experience the phenomenon.
Scientists are paying close attention because the sun remains in the lingering aftermath of its recent solar maximum, which NOAA and NASA estimate peaked in late 2024.
This period of heightened solar activity increases the likelihood of stronger solar storms and more frequent aurora displays.
Tips for Watching the Northern Lights
Experts say the best way to improve your chances of seeing the aurora is to find a dark location away from city lights with a clear view of the northern horizon.
The darker the environment, the more vibrant the colors will appear in the sky.
Skywatchers are also encouraged to monitor real-time aurora forecasts and space-weather tracking apps that follow solar wind conditions and magnetic field activity.
For many people, the possibility of seeing the northern lights is a rare and unforgettable experience, making this upcoming solar event one worth watching closely.
