Solar Action Heats Up with Fresh Flare and CME Headed Earth
• A minor C9.9 solar flare erupted from active region 4274, signaling continued high solar activity.
• There is a 65% chance of minor to moderate radio blackouts and a 15% chance of stronger ones due to recent solar activity.
• The geomagnetic field may reach minor storm levels by November 6–7 due to an approaching high-speed solar wind stream and potential CME.
Solar flare, radio blackouts, geomagnetic storm watch
A minor C9.9 solar flare erupted from active region 4274 at 05:05 UTC on November 5, 2025, following several earlier C-class flares and two powerful X-class eruptions. Solar activity remains high, with a 65% chance of minor to moderate radio blackouts and a 15% chance of stronger ones. The geomagnetic field is currently quiet but may reach minor storm levels by November 6–7 as a new high-speed solar wind stream and possible coronal mass ejection (CME) approach Earth.
