    Geomagnetic activity is forecast to rise sharply, reaching G1 levels by 18:00 UTC and peaking at G2 (Kp 5.67) by 21:00 UTC today. Conditions are expected to return to quiet levels (Kp 3.0) by 00:00 UTC on 10 September.

    🌌 Aurora

    Observers at mid-latitudes (40-60°N) should prepare for potential aurora visibility during the G2 peak between 18:00 and 23:59 UTC.

    Optimal viewing conditions will occur in locations with dark, clear skies away from light pollution.

    👁 Watch for

    Monitor the arrival of the predicted geomagnetic disturbance after 18:00 UTC for potential sudden shifts in the interplanetary magnetic field.
