The Sun’s only visible active region sputtered and spurted and eventually unleashed a small solar flare on Feb. 7, captured here by our Solar Dynamics Observatory satellite. The flare appears as a brief, bright flash about midway through the half-day-long clip. Normally, a flare this small might not catch much attention, but solar activity is increasingly rare as the Sun is slowly approaching solar minimum, a natural low point in its 11-year activity cycle.

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,

SOLAR ACTIVITY IS HIGH: Suddenly, the sun is very active. Yesterday, Earth-orbiting satellites detected two powerful X-class solar flares. This interest-compressed movie from NASA's Solar Dynamics Observatory shows both: The northern flare ( X 1. 8 ) came from active sunspot 4274. The southern flare ( X 1. 1 ) came from a sunspot hidden behind the sun's limb. It was probably more powerful than its nominal classification because the flare was partially eclipsed by the edge of the solar disk. Ther

Solar Activity Report: November 17-23, 2025 Solar activity remained at low levels throughout the reporting period, predominantly within the B-class flare range. Four high-intensity C-class flares and several weaker C-class events were observed, with the largest—a C9.9—occurring on November 19 from a region just beyond the northeast limb. No Earth-directed CMEs were detected during this interval. The latest helioseismic far-side map indicates the presence of two active regions, both with a high p
