QUIET

Geomagnetic activity has transitioned from quiet to unsettled and active states following a surge in the Kp-index. Current conditions are characterized by a Kp of 3.7 with a forecast of peak G2 activity early in the window.

⚠ Kp 5 (G1) expected · 4 more below
Next 24 h

We anticipate a brief period of G2-level geomagnetic storming around the start of this forecast window. Activity is expected to subside to unsettled (Kp 3-4) levels by 18:00 UTC and remain there through the remainder of the 24-hour period.

🌌 Aurora

At a Kp of 3.7 to 5.6, aurora observers at high latitudes should be alert for visible displays.

Mid-latitude observers (40-60°N) may experience limited visibility during the peak window, though lower-mid latitudes are unlikely to see significant activity.

👁 Watch for

Watch for the predicted Kp 5.67 peak and subsequent decline, as the strength of the G2 pulse will determine the potential for utility grid fluctuations or minor satellite orientation anomalies.
