A coronal mass ejection (CME) produced by the August 30, 2025, long-duration M2.7 solar flare impacted Earth at 21:01 UTC on September 1, producing G1 \u2013 Minor to G2 \u2013 Moderate geomagnetic storm conditions.<\/strong><\/p>\n<\/div>\n

A coronal mass ejection (CME) associated with the long-duration M2.7 solar flare on August 30 impacted Earth\u2019s magnetosphere at 21:01 UTC on September 1. The impact caused an abrupt increase in solar wind speed to between 600 and 675 km\/s and raised the total interplanetary magnetic field (Bt) to 20\u201326 nT.<\/p>\n

The initial response included a G1 \u2013 Minor geomagnetic storm onset at 21:08 UTC, followed by G2 \u2013 Moderate geomagnetic storming at 22:41 UTC, according to NOAA\u2019s Space Weather Prediction Center (SWPC).<\/p>\n
