    QUIET

    Solar activity is currently low with the magnetic field in a largely stable state. A slight increase in geomagnetic activity is expected later in the day, though no significant storming is forecast.

    Expect geomagnetic conditions to trend toward an unsettled state (Kp ~3) by 12:00 UTC as space weather parameters shift. Flare activity will likely remain capped at low C-class levels, with a 15% probability of isolated M-class events.

    🌌 Aurora

    Aurora visibility is not expected at mid-latitudes (40-60°N) given the current Kp-index forecast.

    more

    Observers at high latitudes may see minor activity, but clear skies and high-latitude proximity are required for any visual confirmation.

    👁 Watch for

    Monitor the evolution of AR4551, as it remains the only region with a magnetic configuration capable of producing moderate flare activity within the next 24 hours.
