QUIET

Geomagnetic activity has retreated to unsettled levels following a period of G2-class storming over the last 24 hours. The solar disk remains moderately active with several active regions, though X-ray output is currently stable.

Geomagnetic conditions are expected to remain unsettled, with the Kp-index likely fluctuating between 3 and 4 over the next 24 hours.

more

No significant solar radiation storms or major radio blackouts are anticipated as solar flare probabilities remain low.

🌌 Aurora

Aurora activity will be largely restricted to high-latitude regions.

more

Observers at mid-latitudes (40-60°N) are unlikely to see significant displays unless geomagnetic conditions shift unexpectedly higher.

👁 Watch for

Monitor the magnetic complexity of AR4545 as it rotates, as any evolution in its magnetic classification could lead to increased flare potential.
