SEVERE GEOMAGNETIC STORM WATCH: <\/span><\/strong>A CME is heading straight for Earth–see below. NASA and NOAA models agree that it will strike Earth on June 1st<\/strong>. The impact could spark a severe (G4<\/a>-class) geomagnetic storm with auroras visible across Europe and many US states. This won’t be as big as the famous May 2024 storm<\/a>, but it could be one of the bigger events of Solar Cycle 25 if a severe storm materializes. CME impact alerts:<\/strong> SMS Text<\/a><\/p>\n

MAJOR <\/span> SOLAR FLARE AND HALO CME: <\/span><\/strong>Big old sunspot 4100 finally exploded–and it was a doozy. On May 31st at 00:05 UTC, Earth-orbiting satellites detected an M8.2-class solar flare. The explosion lasted more than 3 hours:<\/p>\n

\nA long-duration M8.2-class solar flare recorded by NASA’s Solar Dynamics Observatory<\/span><\/p>\n

Although the flare was not technically X-class, it was close. Moreover, it was a slow explosion with lots of power “under the curve.” The blast was able to lift a massive CME out of the sun’s atmosphere.<\/p>\n

Indeed, shortly after the flare, SOHO coronagraphs recorded a bright halo CME heading directly for our planet:<\/p>\n

This is a very fast-moving CME. Type II radio emissions from shock waves within the cloud suggest it is traveling 1,938 km\/s or 4.3 million mph. When it strikes Earth, the CME could spark severe geomagnetic storms with auroras at mid- to low latitudes. Stay tuned!
