    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.

    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.
