    Next 24 h

    Geomagnetic conditions are expected to remain quiet for the next 24 hours, with the Kp-index likely to settle near 1.0.

    more

    Flare probability for C-class events remains moderate, while the risk for further M-class activity persists primarily from AR4524.

    🌌 Aurora

    Aurora visibility is restricted to high-latitude regions, specifically near the poles.

    more

    Mid-latitude observers (40-60°N) should not expect any significant auroral displays during this period.

    👁 Watch for

    Monitor the evolution of AR4524 as it moves across the solar disk, as its potential for further M-class flares remains the primary driver of transient solar activity.
