O Solar Dynamics Observatory da NASA capturou esta imagem de uma erupção solar – como visto no flash brilhante no centro da imagem – em 4 de maio de 2022. A imagem mostra um subconjunto de luz ultravioleta extrema que destaca o material extremamente quente em erupções e que é colorido em amarelo. Crédito: NASA/SDO
Nas últimas 24 horas, o Sol emitiu duas erupções solares de classe M e uma de classe X. Na escala usada para classificar as explosões solares, a classe X é a mais intensa e a classe M está um nível abaixo disso. Isso vem na esteira de várias outras grandes explosões.
O Sol emitiu uma erupção solar moderada em 4 de maio de 2022, com pico às 5:00 am ET.[{” attribute=””>NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. This flare is classified as an M-class flare.
NASA’s Solar Dynamics Observatory captured this image of a solar flare – as seen in the bright flash in the lower-left portion of the image – on May 3, 2022. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares, and which is colorized in yellow. Credit: NASA/SDO
The Sun emitted a moderate solar flare on May 3, 2022, peaking at 8:19 p.m. ET. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. This flare is classified as an M-class flare. M-class flares are a class below the most intense flares, the X-class flares.

The Sun emitted a strong solar flare on May 3, 2022, peaking at 9:25 a.m. EDT. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. This flare is classified as an X-class flare. X-class denotes the most intense flares, while the number provides more information about its strength.
Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, and navigation signals. They also pose risks to spacecraft and astronauts. More info on how flares are classified can be found here.
This animation of the Solar Dynamics Observatory shows it above the earth as it faces toward the Sun. SDO is designed to help us understand the Sun’s influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.

Please visit NOAA’s Space Weather Prediction Center, the U.S. government’s official source for space weather forecasts, watches, warnings, and alerts, to see how such space weather may affect Earth. NASA serves as the nation’s space weather research arm. NASA constantly monitors the Sun and our space environment with a network of spacecraft that investigate everything from the Sun’s activity to the solar atmosphere, as well as the particles and magnetic fields in the space surrounding Earth.
