NOAA's Space Weather Prediction Center (SWPC) warned Wednseday that a super fast Earth-facing coronal mass ejection (CME) erupted from the sun at a speed of 1200 to 1300 km/s and would spark a severe (G4) geomagnetic storm on Thursday, potentially disrupting critical assets on the grid that are crucial for powering modern society.
According to SWPC's website, the space weather event will "likely arrive at Earth on 10 October," adding, "We won't know the characteristics of the CME until it arrives 1 million miles from Earth and its speed and magnetic intensity are measured by the DSCOVR and ACE satellites."
The NOAA Geomagnetic Storm Scale indicates a G4 storm can disrupt "key assets" on the grid... SWPC's Aurora forecast for tomorrow shows that northern lights will be visible as low as the Pacific Northwest, Midwest, Mid-Alantic, and Northeast.
"Today's incredible X9.0-class solar flare, the most intense flare since 2017. An Earth-directed solar storm is highly likely, given the spot region is faced directly at Earth," Space Weather Watch wrote on X.
All this solar activity comes as Solar Cycle 25 has reached a maximum period.
