SLOW SOLAR FLARE: Solar flares occur when magnetic fields get tangled. Lines of magnetic force above sunspots criss, cross, and explode in a flash of electromagnetic radiation. This process, called "magnetic reconnection", usually happens in a matter of minutes. Earlier today (June 7th), NASA's Solar Dynamics Observatory witnessed an explosion that took two hours to unfold. This leisurely C1-class solar flare happened in the magnetic canopy of sunspot AR2661. Often, slow explosions like this one

Today’s BIG solar flare is causing all these amazing northern lights. It peaked at X5.1 intensity—the strongest flare of 2025 so far and the most powerful since an X9.0 event in October 2024. Solar flares are ranked by their X-ray brightness in 5 classes (A, B, C, M, X), with each class representing a 10x increase in energy output. Within the X class (the most intense), the number indicates further strength. - X1: Baseline strong flare. - X5: About 5x stronger than X1, releasing energy equivalen
