Sun Releases Second Strong Solar Flare on Same Day | NASA SDO

The Sun emitted a second strong solar flare, peaking at 11:27 a.m. ET on Aug. 5, 2024. NASA’s Solar Dynamics Observatory watches the Sun constantly and it captured an image of the event.

The bright flash of a solar flare appears on the Sun's lower left in an ultraviolet view of the Sun. The Sun is dotted with darker and brighter regions and wispy loops of bright solar material.

NASA’s Solar Dynamics Observatory captured this image of a solar flare—seen as the bright flash on the lower left of the first image–on Aug. 5, 2024. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares. It is colorized in gold. 

The Sun's outer atmosphere, the corona, is structured by strong magnetic fields. Where these fields are closed, often above sunspot groups, the confined solar atmosphere can suddenly and violently release bubbles of gas and magnetic fields called coronal mass ejections (CMEs). A large CME can contain a billion tons of matter that can be accelerated to several million miles per hour in a spectacular explosion. Solar material streams out through the interplanetary medium, impacting any planet or spacecraft in its path. CMEs are sometimes associated with flares but can occur independently.

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

NASA works as a research arm of the nation’s space weather effort. NASA observes the Sun and our space environment constantly with a fleet of spacecraft that study everything from the Sun’s activity to the solar atmosphere, and to the particles and magnetic fields in the space surrounding Earth.
