As 2025 draws to a close, sky gazers may be treated to a mesmerizing display of the northern lights, thanks to a coronal mass ejection (CME) making its way towards Earth. The expected interaction with our geomagnetic field will likely lead to a weak G1-strength geomagnetic storm this Wednesday night. This phenomenon creates an opportunity for viewers to catch a glimpse of the aurora borealis as the New Year approaches.
The most vivid displays of the northern lights will be seen across Northern Canada, particularly in the northern regions of Western and Eastern Canada. However, individuals in southern areas may still be able to witness fainter lights, with the highest chances in Western Canada and northwestern Ontario.
Optimal viewing times will fall between 6 p.m. to 12 a.m. CT, or 5 p.m. to 11 p.m. MT. Though the anticipation is high, weather conditions may present a challenge as much of Western Canada is forecasted to experience extensive cloud cover overnight. Fortunately, parts of southern Alberta and British Columbia should enjoy clearer skies, offering better prospects for viewers, while southern Saskatchewan and Manitoba may be less fortunate. In contrast, clear conditions are expected to persist over northwestern Ontario, enhancing the likelihood of a spectacular light show.
This celestial event serves as a reminder of the wonders of our universe and offers a hopeful way to ring in the New Year.
