    Quiet geomagnetic conditions persist with elevated flare probability
    SOLAR: MODERATE
    GEO: QUIET

    Active Regions
    4
    X-Ray
    A/B (quiet)

    Geomagnetic conditions remain quiet as solar activity continues at a low, stable baseline. While the planetary K-index remains low, the high probability for M-class flares suggests the potential for increased activity in the coming 48 hours.

    sfu · >150 = high activity

    The Earth’s magnetic field is currently undisturbed with a Kp-index of 1.0. Solar activity is characterized by 29 active regions across the disk, though currently displaying minimal explosive potential beyond minor C-class events. The 10.7cm radio flux is holding steady at 98.0 sfu, consistent with a moderate but non-strenuous solar cycle phase.

    Key Metric

    The 65% probability of M-class flares is the primary metric, as a significant eruption could rapidly transition space weather conditions from quiet to active.

    Geomagnetic activity is expected to remain at quiet levels, with Kp indices hovering between 1 and 2. While major storms are not anticipated, the 65% probability of M-class flares warrants monitoring for sudden radio blackout events on the sunlit side of Earth.

    🌌 Aurora Outlook

    Aurora visibility is not expected for mid-latitudes. Observers in high-latitude regions may see standard, quiet-time auroral displays, but no storm-driven enhancements are currently forecasted.

    Monitor the X-ray flux for any rapid escalation in intensity from the four primary active regions, which would indicate a heightened risk for short-wave radio propagation interference.
