Next 24 h

Expect continued unsettled conditions with Kp index values oscillating between 4.3 and 4.7 over the next 24 hours. Minor G1 geomagnetic disturbances are possible, particularly during the upcoming night-side transits.

🌌 Aurora

Aurora visibility is restricted to high latitudes.

Observers in northern Canada, Scandinavia, and parts of Alaska may catch faint displays, but mid-latitude sightings remain unlikely under current conditions.

👁 Watch for

Monitor the Kp index for a sustained push into G1 (Kp 5) levels, which would indicate a potential uptick in auroral intensity for high-latitude observers.
