Next 24 h

Geomagnetic activity is forecast to rise slightly to Kp 3 over the next 12 hours, remaining in the unsettled category. No significant geomagnetic storms are expected, and flare activity will likely persist at a low, sporadic C-class level.

🌌 Aurora

Aurora visibility is not expected for mid-latitudes (40-60°N) given the current and forecasted geomagnetic indices.

more

Observers at high polar latitudes may see faint or isolated auroral activity during the peak of the unsettled period.

👁 Watch for

Monitor AR4549 for any sudden increase in magnetic complexity, as it has been the primary contributor to today’s C-class flare activity.
