| G4 (Severe) Geomagnetic Storming Observed / NOAA / NWS Space Weather Prediction Center A G4 geomagnetic storm was observed at 0257 UTC Tuesday. | Tuesday, September 17, 2024 03:54 UTC |
| Sun Releases Strong Flare – Solar Cycle 25 </>The Sun emitted a strong solar flare, peaking at 11:29 a.m. ET on Sept. 14, 2024. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.</>
</>A combination of multiple ultraviolet wavelengths shows the Sun with bright loops of material extending off of the surface. A bright flash erupts on the Sun's lower left, and a burst of material is thrown off of the Sun into space.</>NASA’s Solar Dynamics Observatory captured this image of a solar flare — seen as the bright flash near the center of the image – on Sept. 14, 2024. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in gold and red. Credit: NASA/SDO</>
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.</></>This flare is classified as an X4.5 flare. X-class denotes the most intense flares, while the number provides more information about its strength.</></>To see how such space weather may affect Earth, please visit NOAA’s Space Weather Prediction Center https://spaceweather.gov/, the U.S. government’s official source for space weather forecasts, watches, warnings, and alerts. 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. | September 16, 2024 |
