A strong X1.9 solar flare erupted from the sun's surface at 9:49 p.m. ET on Nov. 30, and NASA’s Solar Dynamics Observatory caught it in action. The flare appears as a bright flash on the Sun’s edge, followed by a plume of hot material rising into space. Solar flares are powerful bursts of energy. They can disturb radio communications, affect navigation signals, and pose risks to spacecraft and astronauts — which is why NASA and NOAA track them so closely. Credit: NASA/SDO | Space 360

The Sun just unleashed a surge of solar activity as the massive AR 4294 sunspot rotates directly toward Earth, and the timing could not be more intense. This enormous active region is now one of the largest of Solar Cycle 25, with NOAA and NASA confirming rapid magnetic growth, flare potential, and increased CME activity. Space weather trackers around the world are watching closely as the region’s complex magnetic structure faces our planet, raising questions about what this means for aviation,
