Summary
Five M-class flares erupted from sunspot AR4513 on August 25, capped by an M7 burst, making the region the main source of flaring on the Earth-facing sun over the past day.
AR4513 is rotating further into Earth-facing view with a complex, unstable magnetic field, prompting forecasters to put the odds of more M-class flares at 55% and X-class events at 5% in coming days.
M-class flares can trigger minor to moderate radio blackouts on Earth’s sunlit side, and an earlier M6.9 flare from the same region on August 25 already sent a CME toward Earth with a possible glancing arrival on August 28.
AR4513 had already produced an M8.1 flare on August 20, but that CME missed Earth; with Solar Cycle 25 near peak, forecasters say any Earth-directed CME this week could bring high-latitude auroras and wider communication risks.
