Active Regions
10
X-Ray
A/B (quiet)

Geomagnetic conditions are currently quiet with a Kp-index of 2.3. Solar activity is stable, characterized by minor C-class flare probability and moderate F10.7 radio flux.

The sun is exhibiting low-level activity, with no significant geomagnetic disturbances reported. We are observing 10 active regions across the solar disk, though none show complex magnetic configurations. Current X-ray flux remains in the background B-class range, following a minor C-class event earlier today.

Key Metric

The current Kp-index of 2.3 is the most significant metric, confirming that Earth’s magnetic environment remains undisturbed and stable.

Conditions are expected to remain quiet over the next 24 hours. The Kp-index is forecast to hold steady near 1.3, indicating negligible impact on the Earth’s magnetosphere.

🌌 Aurora Outlook

Aurora activity will be limited to high-latitude regions, typical for quiet solar conditions. Mid-latitude observers should not expect visible displays at this time.
