Sun news: Is a CME striking Earth now?
Sun news August 8, 2026: The expected CMEs arrived late, but the solar wind and IMF ticked up this morning. Active conditions and isolated G1 storms are possible. The post Sun news: Is a CME striking Earth now? first appeared on EarthSky .
On August 8, 2026, a coronal mass ejection (CME) from the sun arrived at Earth, causing a minor geomagnetic storm. The solar wind, interplanetary magnetic field (IMF), and Bz component all showed low levels throughout the day, but began increasing around 6 UTC on August 8. Forecasters anticipate mild disturbances to Earth's magnetic field, up to active levels (Kp 4), and isolated G1 geomagnetic storming cannot be ruled out.
No new CMEs were observed in coronagraph imagery over the past day, and flare activity remained low, with only five B flares produced by active region AR4504 during the past 24 hours. AR4504's beta-gamma magnetic configuration may become a key player in the coming days.
