    QUIET

    Geomagnetic conditions are currently quiet, following a period of minor, transient instability. Solar activity is characterized by a moderate F10.7 flux and limited flare production across the visible disk.

    Expect geomagnetic conditions to remain in the quiet range, with the Kp index likely fluctuating between 1 and 3 over the next 24 hours.

    more

    Solar flare activity will likely persist at low levels, with an 85% probability of additional C-class flares.

    🌌 Aurora

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

    more

    No significant displays are expected at mid-latitudes (40-60°N) given the current quiet geomagnetic forecast.

    👁 Watch for

    Monitor active region AR4535 for any sudden changes in magnetic complexity, as it currently holds the most potential for increased flare output in the coming day.
