Solar flare potential remains moderate for C-class events, while the probability of stronger M-class flares stays capped at 45%.

🌌 Aurora

Aurora visibility is not expected for mid-latitudes (40-60°N).

more

Observers at very high latitudes may see minimal, stable auroral activity, but conditions are not favorable for widespread displays.

👁 Watch for

Monitor active region AR4513 for any sudden magnetic complexity evolution, as it holds the highest potential for flare activity on the solar disk.
