Sunspot AR4366 Sparks Intense Solar Flare Activity
• Powerful X8.3 solar flare, the strongest of 2026, erupted from sunspot AR
• Solar flares caused strong R3 radio blackouts in the South Pacific, including eastern Australia and New Zealand.
• Rapid growth and magnetic complexity of sunspot AR4366 suggest more eruptions and potential coronal mass ejections are likely.
Sun unleashes series of powerful solar flares
The Sun has been extremely active, unleashing a series of powerful solar flares in the last 24 hours. Among these was an X8.3 flare, which is the strongest solar flare observed in 2026 so far. This significant event has been attributed to sunspot region AR4366, which scientists have described as a 'solar flare factory' due to its high level of activity.
