Stargazers have a chance to witness a dazzling display of the northern lights tonight, as a potent solar event is set to unfold on Monday evening. The recent eruption from the sun, an X 1.9 flare followed by a coronal mass ejection (CME), has captured the attention of the U.S. Space Weather Prediction Center (SWPC). This particular flare stood out due to its prolonged duration over several hours, making it more impactful than usual for its magnitude.
CMEs, which are massive bursts of solar particles traveling swiftly on the solar wind, have the potential to interact with Earth’s magnetic field and create stunning auroras like the aurora borealis in the northern hemisphere. Fortunately, Earth is directly in the path of this CME, promising a vibrant celestial spectacle.
The SWPC has announced that the CME is expected to reach Earth between late January 19 and early January 20. This event is projected to induce a severe geomagnetic storm, rated as a G4 on the storm intensity scale. Comparatively, previous geomagnetic storms in May 2024 and October 2024 were classified as G5 storms, resulting in mesmerizing light displays reaching as far south as the Caribbean.
While the northern lights are typically visible in more northern latitudes, under certain conditions, they can be observed further south. To catch a glimpse of this phenomenon, the auroral hole, through which the CME particles travel, must shift southward. Additionally, clear skies and darkness are essential for optimal viewing conditions. Despite higher cloud coverage during this season, enthusiasts are encouraged to seek out dark, cloud-free locations for the best chance of witnessing the auroras.
For those eager to track the visibility of the aurora borealis in their area, handy apps like Aurora Alerts and Aurora Forecast can provide real-time updates. This extraordinary cosmic event offers a unique opportunity for skywatchers to experience the grandeur of the northern lights, making it a night to remember.
