⚠ Kp 4 expected · 4 more below
Geomagnetic activity is forecast to increase rapidly, peaking at a Kp of 5.67 (G2 storm level) by 21:00 UTC today. Conditions are expected to return to quiet levels shortly after midnight, as the current impulse passes.
Observers at high latitudes should be prepared for auroral activity starting late this evening.

For mid-latitudes, there is a moderate possibility of viewing the aurora near the horizon during the peak of the G2 event, specifically between 20:00 and 00:00 UTC.
Monitor the actual Kp values between 18:00 and 22:00 UTC to confirm if the forecasted G2 threshold is reached.
