Geomagnetic activity is expected to increase to Kp 4 (unsettled) by midday today. Solar flare probabilities remain modest, with a 60% chance for C-class events and minimal risk of more significant M or X-class eruptions.

🌌 Aurora

Aurora activity is expected to remain restricted to high latitudes.

Observers at mid-latitudes are unlikely to see displays, as geomagnetic indices are currently projected to stay below the storm threshold.

👁 Watch for

Monitor the development of AR4560 as it rotates toward the solar limb for any sudden changes in magnetic complexity.
