    Geomagnetic activity is expected to rise slightly, peaking near Kp 4.67 (G1 threshold) around 21:00 UTC today. Conditions should return to more stable, unsettled levels by early tomorrow as the influence of current solar structures wanes.

    🌌 Aurora

    At a projected Kp of 4.67, aurora visibility is unlikely for mid-latitudes (40-60°N).

    more

    Observers at high latitudes may see modest activity, but generally, the atmospheric display is expected to remain limited.

    👁 Watch for

    Monitor the geomagnetic index around 21:00 UTC to see if the solar wind parameters push the Kp-index into the G1 storm category as forecast.
