    Geomagnetic activity is expected to peak between 18:00 UTC and 21:00 UTC, reaching Kp 4.67. Conditions are forecast to subside to Kp 3.33 by the start of the new day as the influence of the current solar wind structure wanes.

    🌌 Aurora

    Aurora visibility is restricted to high latitudes.

    Observers at latitudes above 60°N may see faint auroral displays during the peak window this evening, but mid-latitude sightings are unlikely.

    👁 Watch for

    Monitor the geomagnetic index for any unexpected transition into G1 storm thresholds (Kp 5) during the 18:00-21:00 UTC window.
