Geomagnetic conditions will remain at quiet levels, with the Kp-index forecasted to stay near 1.3 throughout the next 24 hours.

more

Solar flare activity will likely be confined to minor C-class events, posing no significant impact to Earth’s infrastructure.

🌌 Aurora

Aurora visibility is restricted to high-latitude polar regions.

more

Observers at mid-latitudes (40-60°N) should not expect any auroral activity during this period.

👁 Watch for

Monitor the development of AR4535 as it nears the western limb; while current flare probability is low, any sudden magnetic complexity could briefly elevate radio noise levels.
