The planetary K-index is currently at 0.7, reflecting a stable and quiet magnetosphere. Solar flux (F10.7) sits at 98.0 sfu, indicating low levels of solar activity. Despite having eight active regions on the disk, the X-ray background remains at A/B levels, with no significant eruptions observed in the last 12 hours.

Key Metric

The X-class flare probability of 35% is the most important metric, as it highlights a latent risk for significant activity despite currently quiet conditions.

Geomagnetic conditions are expected to remain at quiet levels, with Kp values unlikely to exceed 2.33. No significant solar disturbances are anticipated, ensuring stable operations for satellite and radio communications.

🌌 Aurora Outlook

Aurora activity is currently restricted to high latitudes. Observers at mid-latitudes (40-60°N) should not expect any visible auroral displays in the next 24 hours.
