SpaceSun news: Surprise M flare heralds an old region’s return Posted on August 23, 2025 by Administrator he sun unleashed a long-duration M flare at 18:51 UTC on August 22. It surprised everyone and pushed solar activity to moderate. The blast came from an incoming, still-unnumbered region just over the sun’s southeast horizon. The flare triggered an R1 (minor) radio blackout over the Pacific Ocean southwest of Mexico and produced a Type II radio emission. Evidence suggests this may be the return of an old, magnetically complex region that previously fueled fiery activity on the sun’s far side. We’ll keep watch, as it rotates into view and earns its new sunspot number.
