    UNSETTLED

    Solar activity remains in a quiet-to-unsettled phase as the geomagnetic field holds steady. While current conditions are benign, the presence of multiple active regions sustains a significant probability of moderate solar flares.

    Geomagnetic conditions are expected to remain largely unsettled, with a brief uptick to Kp 3.67 anticipated later today.

    Solar flare activity remains the primary focus, with a 70% probability of M-class flares occurring as active regions continue to develop.

    🌌 Aurora

    Aurora visibility is not expected at mid-latitudes.

    more

    Observers in high-latitude regions may see minor activity, but clear conditions are required for optimal viewing.

    👁 Watch for

    Monitor the magnetic complexity of AR4498 and AR4500, as their evolution will dictate the likelihood of impulsive M-class flare events in the next 24 hours.
