Geomagnetic activity is forecast to rise to Kp 3.67 by late today as the influence of ongoing solar wind conditions persists.

No major radio blackouts or radiation storms are anticipated, though M-class flare probability remains moderate at 55%.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes for the next 24 hours.

Observers in high-latitude regions may experience brief, minor fluctuations if Kp levels reach the predicted unsettled threshold.

👁 Watch for

Monitor AR4494 for any signs of magnetic complexity growth, as it remains the most likely source for further M-class flare activity.
