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

• A Prominence Eruption with a M-class Solar Flare • We can see prominence erupting to interplanetary space. A flare occurs simultaneously at the bottom region of the eruption.

• Full Disc - Solar Flare - Prominence Eruption and CME Event (304 angstroms) 24.12.2020 • In 2011 June, one of the most spectacular solar sights is an explosive flare. The Sun unleashed a somewhat impressive, medium-sized solar flare as rotation carried active regions of sunpots toward the solar limb. That flare, though, was followed by an astounding gush of magnetized plasma -- a monster filament seen erupting at the Sun's edge in this extreme ultraviolet image from NASA's Solar Dynamics Obser
