Geomagnetic conditions are currently unsettled with a Kp-index of 3.7. A brief period of G1-level disturbance is expected late in the 24-hour cycle as solar wind conditions evolve.
⚠ Kp 4 expected · 3 more below
Expect geomagnetic conditions to peak at a G1 (Minor) level around 21:00 UTC today before subsiding.

Flare probabilities remain skewed toward C-class events, though the 55% chance for M-class activity warrants continued monitoring of AR4536 and AR4538.
Aurora visibility is restricted to high latitudes.

Observers in Scandinavia, Canada, and high-latitude US states may see faint displays during the peak window this evening, but mid-latitude sightings are unlikely.
Monitor the evolution of AR4536 and AR4538 for sudden magnetic complexity, as they currently represent the highest potential for M-class flare activity.
