Limited regions in the northern U.S. get a chance to witness the aurora borealis tonight
- NASA and NOAA report that solar maximum activity has caused increased aurora visibility in North America.
- The strongest auroras seen in the last 500 years result from this heightened solar activity, particularly during geomagnetic storms.
- Aurora displays are expected to continue being visible throughout 2025 and into early 2026, providing more chances for observation.
In December 2024, NASA and the National Oceanic and Atmospheric Administration (NOAA) announced an unprecedented uptick in solar activity. This surge, identified as part of the sun's 11-year solar cycle, reached its peak, leading to the most vibrant displays of the aurora borealis in five centuries. The phenomenon is particularly evident in regions like Alaska and northern Canada, where auroras are typically visible most frequently. However, due to this heightened solar activity, areas further south in the northern U.S. have also experienced stunning auroral events, allowing for more widespread viewing opportunities. The peak solar activity occurred after a series of significant solar events earlier in the year. In May 2024, the strongest geomagnetic storm witnessed in two decades prompted brilliant displays of northern lights that reached as far south as northern Florida. Such occurrences linked to the solar cycle's solar maximum create elevated geomagnetic conditions, contributing to the frequency and intensity of aurora sightings when conditions are favorable. In the weeks leading up to this announcement, the solar activity showed consistent resilience, showcasing the enduring influence of solar maximum output through 2025, and even expected reaching into early 2026. Observers in northern U.S. states such as North Dakota, Minnesota, and parts of Idaho reported multiple opportunities to witness the auroras on more than one occasion each month during this period. Enhanced geomagnetic storms could potentially expand viewing opportunities even further, depending on the severity of solar events. The ability to observe the northern lights from greater distances than usual stems from optimal conditions, including clear skies and regions with minimal light pollution. Those aiming to catch a glimpse of the breathtaking phenomenon are advised to venture to locations further north, particularly during peak hours between 10 p.m. and 2 a.m. As interest in the aurora borealis continues to grow, so does NASA’s commitment to studying the intricate relationship between solar activity and auroral behavior, aiming to enhance predictive capabilities for future events.
