The storm that began on December 31, 2024, is expected to reach a peak intensity of K-INDEX 7, indicating a strong geomagnetic storm. By January 1, 2025, the storm's intensity is anticipated to decrease to K-INDEX 5, which will still classify it as a significant geomagnetic storm.
This solar storm may lead to stunning auroras, potentially creating a "solar fireworks" display visible in certain parts of the world, coinciding with the New Year celebrations.
Although this storm originated from an X1.1 class flare, one of the most powerful types of solar flares, it is not the largest flare of 2024.
This distinction belongs to the X9 class flare that occurred on October 3, 2024. It was the third largest since 2011 and the fifth largest since 2005.
