QUIET

Geomagnetic activity is trending upward with a Kp-index of 3.3, reaching threshold levels for G1-class storming in the next few hours. While solar flare activity remains low, current interplanetary conditions are favorable for increased geomagnetic response.

Expect geomagnetic conditions to peak near Kp 5 (G1 minor storm) around 06:00 UTC before gradually declining back to unsettled levels by the afternoon.

Flare activity is expected to remain low, with a 35% probability of isolated C-class eruptions.

🌌 Aurora

Aurora visibility is restricted to high latitudes.

Observers in northern Canada, Scandinavia, and similar latitudes may catch views of auroral activity as the Kp index reaches the G1 threshold; mid-latitude viewing is unlikely.

👁 Watch for

Monitor the Kp-index trend between 06:00 and 09:00 UTC for confirmation of storm intensity and potential further geomagnetic escalation.
