QUIET

Geomagnetic conditions remain currently unsettled at Kp 3, though activity is expected to subside in the coming hours. Solar flare activity remains low, characterized by minor C-class events.

⚠ Kp 4 expected · 4 more below
Next 24 h

Conditions are expected to return to quiet levels within the next 6 hours, with the Kp-index dropping to 2 by mid-morning. No significant geomagnetic or radiation storms are projected for the next 24-hour window.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes (40-60°N) as geomagnetic levels are insufficient for equatorward expansion of the auroral oval.

Observers at very high latitudes may see minor activity.

👁 Watch for

Monitor the magnetic complexity of AR4513 and AR4518 for sudden evolution; while current flare probability is low, these regions remain the primary drivers of solar activity.
