Geomagnetic activity is forecast to escalate into G2 (moderate) storm levels over the next several hours. This follows recent instability and an earlier M-class flare, marking a shift toward active space weather conditions.
⚠ Kp 4 reached · 4 more below
Geomagnetic conditions are expected to peak at Kp 6 (G2) between 18:00 UTC today and 00:00 UTC. Conditions should begin to subside back to quiet levels by early tomorrow as the current solar wind structure passes Earth’s magnetic field.
Observers at higher mid-latitudes, particularly in Canada and Scandinavia, should prepare for potential aurora displays during the peak window this evening.

Visibility for lower mid-latitudes remains unlikely, though clear skies in northern-tier regions may offer improved viewing if the G2 threshold is sustained.
Monitor for any secondary M-class or X-class flare signatures from active region AR4549, as its position and magnetic complexity warrant continued observation.
