On Monday night, sky gazers with clear skies may witness a captivating display of the northern lights. The U.S. Space Weather Prediction Center reported a strong X 1.9 flare from the sun, followed by a coronal mass ejection (CME). This prolonged flare, lasting for several hours, was more potent than usual for its magnitude.
CMEs, which are rapid solar wind particle emissions, can interact with Earth’s magnetic field, creating stunning northern lights, also known as aurora borealis. Fortunately, Earth is in the trajectory of this recent CME event.
The SWPC has predicted that the CME is expected to reach Earth between late January 19 and early January 20 EST. Geomagnetic storms, disturbances to Earth’s magnetosphere, are categorized from G1 (minor) to G5 (extreme). The forecast indicates a severe G4 storm, suggesting significant activity.
Previous G5 storms in May 2024 and October 2024 produced remarkable auroras, visible as far south as the Caribbean. Typically, aurora borealis are seen in northern regions, but under specific conditions, they can be observed farther south.
For optimal viewing, dark, cloud-free locations are ideal. With the severity of this forecast, the aurora borealis may be visible even if not facing north. Apps like Aurora Alerts and Aurora Forecast can help track visibility in your area.
While this time of year may not be ideal due to increased cloud cover, capturing the northern lights during this event could be a rare and memorable experience.
