As the final hours of 2023 approach, parts of the northern United States might be treated to an awe-inspiring display of the northern lights, a natural phenomenon sparked by solar activity. According to the U.S. National Oceanic and Atmospheric Administration (NOAA), two coronal mass ejections (CMEs)—massive bursts of plasma and magnetic fields from the sun—are heading toward Earth. These solar storms are expected to arrive early this week, potentially igniting vibrant auroras on Monday and Tuesday nights.
Residents in northern states like Alaska, Washington, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, New Hampshire, Vermont, and Maine are among those most likely to witness the spectacle. Even parts of Oregon, Idaho, Wyoming, Iowa, and New York might catch a glimpse. NOAA advises that the early morning hours of Tuesday, January 2, while the sky remains dark, will offer the best opportunity to view the display. For real-time updates, NOAA’s Space Weather Prediction Center website and aurora forecasting apps are valuable resources.
The northern lights, or aurora borealis, occur when charged particles from the sun collide with Earth’s magnetic field. This interaction excites particles in the upper atmosphere, producing glowing ribbons of light that shimmer in colors like green, pink, and purple. While typically visible in polar regions, stronger solar storms can extend their reach to lower latitudes, giving those in the continental U.S. a rare chance to experience this phenomenon.
For the best viewing conditions, NOAA suggests heading to a location away from city lights, as light pollution can diminish the intensity of the auroras. Although they are often faint to the naked eye, modern smartphone cameras can enhance visibility and capture vibrant hues that might otherwise be missed.
This event is part of an ongoing surge in solar activity as the sun approaches the peak of its 11-year solar cycle, known as the solar maximum. During this period, solar storms and related auroras become more frequent. Scientists anticipate that this heightened activity will continue into 2024, creating more opportunities for aurora sightings in regions farther south than usual.
While the northern lights are primarily a visual delight, NOAA is also monitoring potential disruptions caused by solar storms. High-frequency radio communications, often used by airlines and amateur radio operators, could experience minor interference. However, NOAA has not indicated any significant risks to infrastructure or safety.
This year has already seen memorable auroral displays. In May, a rare, severe geomagnetic storm brought northern lights to unexpected locations, including parts of the United Kingdom, Germany, New England, and even New York City. That storm, the strongest in over two decades, was a reminder of the sun’s dynamic power to captivate and surprise.
As 2023 draws to a close, the potential for a New Year’s Eve light show provides a unique way to celebrate the arrival of 2024. If the skies are clear and the timing aligns, this celestial event could leave millions in awe, offering a magical start to the new year.
