Northern lights expected to illuminate the U.S. until 2026
The optimal viewing period for the northern lights generally occurs between 10 PM and 2 AM, shortly after sunset or before sunrise.
As the sun enters a phase of increased activity, enthusiasts of stargazing and aurora observation throughout the United States can anticipate enhanced opportunities to experience the stunning Celestial Show known as the northern lights, or aurora borealis, over the forthcoming two years.
The sun operates on an approximate 11-year cycle characterized by alternating periods of heightened and diminished activity. Solar Cycle 25, which commenced in December 2019, is projected to peak between late 2024 and early 2026. During this solar maximum, the sun’s magnetic field attains its highest intensity, resulting in a surge of sunspot activity, solar flares, and coronal mass ejections (CMEs).
These solar phenomena can instigate geomagnetic storms when the charged particles engage with Earth’s magnetic field, causing atmospheric gases to emit light and produce the vibrant displays of the northern lights. The intensity of the geomagnetic storm determines how far south the aurora can be observed from the polar regions.
Space Weather and the Celestial Show: Advancing Scientific Understanding
“The May 10th superstorm may have been just the first of several magnificent displays we experience between now and 2026,” said astronomer Tony Phillips of SpaceWeather.com.
In early May 2024, a significant G5 geomagnetic storm resulted in a remarkable display of the northern lights, observable across nearly all 50 states in the U.S., extending even to Hawaii and Puerto Rico. This extraordinary phenomenon, potentially the most intense in the last 500 years as reported by NASA, indicates a likelihood of more frequent and vigorous aurora sightings in the years ahead.
Although predicting the precise timing and locations of future aurora displays remains challenging beyond a few days, experts advise monitoring space weather forecasts and being ready to venture outdoors at a moment’s notice. The optimal viewing period for the northern lights generally occurs between 10 p.m. and 2 a.m., after sunset or before sunrise, when the sky is dark yet the sun has not completely risen. The aurora is best observed in regions with clear, dark skies, away from urban light pollution, particularly in rural areas of the northern U.S. states.
While the anticipation of increased northern lights sightings is thrilling for many, elevated solar activity may also present certain challenges. Intense geomagnetic storms can interfere with satellite communications, GPS navigation, power grids, and may even pose radiation hazards to astronauts and airline personnel. Nevertheless, the data gathered during these occurrences will enhance scientists’ understanding and forecasting of space weather, ultimately aiding in protecting critical infrastructure and ensuring public safety.
