    ⚠ Kp 4 expected · 4 more below
    Next 24 h

    Geomagnetic conditions are expected to remain quiet with the Kp index likely staying below 2.5. No significant solar radiation storms or radio blackouts are anticipated, as flare probabilities for M and X-class events remain very low.

    🌌 Aurora

    Aurora visibility is not expected at mid-latitudes.

    more

    Observers located at high latitudes may see minor, baseline auroral activity, but conditions are currently unfavorable for significant displays.

    👁 Watch for

    Monitor AR4551 for any structural evolution that might increase its potential for producing further C-class or M-class solar flares over the next 24 hours.
