G3 - Strong Geomagnetic Storm Levels were reached at 1746 UTC (1346 ET) on 17 Aug 2024 due to influence from the CME associated with the X flare that left the Sun on August 14th. Stay tuned to our website at swpc.noaa.gov for updates.

Saturday, 17 Aug, observed G3 (Strong) levels briefly in response to a CME arrival. Conditions quickly weakened as CME passage passed over and beyond Earth. Flare activity continued as well. Visit swpc.noaa.gov for the latest forecasts and information.

Check out these images of an explosive R2 (Moderate) level flare along the solar limb & associated CME - (courtesy of jhelioviewer). This event was quite energetic & led to the creation of a rare loop prominence system. Solar cycle 25 continues to impress!

Quite energetic coronal mass ejections (CME) departed the Sun 1-3 September; however, they are not Earth-directed. Visit swpc.noaa.gov for the latest information, forecasts, and updates.
