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

    more

    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.

    more

    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.
