QUIET

Geomagnetic activity is trending downward after a minor Kp-4 excursion earlier today. Solar activity remains low with minimal flaring potential observed across current active regions.

⚠ Kp 5 (G1) expected · 4 more below
Next 24 h

Geomagnetic levels are expected to continue their decline, dropping to Kp 3.0 or lower as the influence of recent solar wind structures wanes.

more

No significant radio blackouts are anticipated given the low probability for M-class or X-class flares.

🌌 Aurora

Aurora visibility is restricted to high latitudes.

more

Observers at mid-latitudes are unlikely to see significant activity at these levels; only those in polar regions should expect consistent displays.

👁 Watch for

Monitor the evolution of active regions AR4564 and AR4565, as their magnetic complexity could shift, potentially altering flare probabilities.
