ACTIVE

Earth is currently experiencing G1 (minor) geomagnetic storm conditions following a rapid rise in Kp-index. Activity is expected to remain unsettled to active over the next 24 hours as the magnetosphere recovers.

Next 24 h

Expect geomagnetic conditions to persist at G1 levels through the next 24 hours, with periods of Kp 4-5 activity. Solar flare risk remains moderate for C-class events, with a lower 50% probability for M-class flares.

🌌 Aurora

Auroral displays are possible at higher mid-latitudes, particularly across northern Canada and Scandinavia.

Observers in the northern United States should monitor local skies during dark hours, though visibility may be faint and intermittent.

👁 Watch for

Monitor the F10.7 flux and X-ray emission for sudden increases that could indicate a transition from geomagnetic-dominated activity to localized eruptive solar events.
