Solar Flare and Geomagnetic Storm: On December 23, the Sun emitted an M8.9-class solar flare, releasing a massive coronal mass ejection (CME) that collided with Earth’s magnetosphere on Christmas Day, triggering a minor geomagnetic storm.
Minor Geomagnetic Storm (G1-Level): The storm, classified as a G1-level on the geomagnetic scale, is expected to produce visible auroras, though the display will likely be more subtle compared to stronger storms.
Aurora Borealis Visibility: The storm could push the auroras further south than usual, allowing people in parts of the Upper Midwest and northern U.S. to catch a glimpse of the northern lights, especially in regions with clear skies and dark areas free of light pollution.
Regions Likely to See Auroras: States like Northern Michigan, Maine, Minnesota, Wisconsin, and North Dakota are expected to have the best chances of viewing the aurora, particularly in rural, dark areas away from city lights.
Best Viewing Time: The auroras are most visible between 10 p.m. and 2 a.m. local time, with clear skies being crucial for optimal visibility.
How Auroras Form: The auroras are caused by charged particles from the solar wind colliding with Earth’s atmosphere..
Future Solar Activity: The Sun is currently in an active phase of its 11-year solar cycle, which means there may be more solar flares and CMEs in the coming months, leading to potential further aurora displays in the near future.
