• Glorious Days of the Sun with a Clover-shaped Active Region (Sunspot) 5.1.2021 • Forgetting our current Sun conditions for a while, let's take a time trip back to mid-December in 2006, when the XRT made its first X-class flare observations. The AR10930 was a large flare-productive region rotated from the East limb early December in 2006. This region produced a number of intensive flares. However, when the first two X-class flares occurred on December 5th and 6th, XRT was in engineering mode ch

🚨 Solar Flare Alert: Sunspot AR3883 Unleashes an X-Class Flare On November 7, 2024, the Sun emitted an intense X2.3 solar flare from active sunspot AR3883, peaking at 13:40 UTC. This powerful burst of radiation caused brief radio blackouts over the Atlantic. Fortunately, it appears the flare did not trigger a significant coronal mass ejection (CME), sparing Earth from magnetic disruptions. However, with Solar Cycle 25 in an active phase, more solar activity could follow, potentially enhancing a
