The solar environment is currently in a quiet state across all observational metrics. While 26 active regions are present on the disk, overall flare production remains low, with only minor C-class activity recorded in the last 12 hours. The F10.7 solar radio flux is at 129.0 sfu, indicating moderate levels of solar irradiance.

Key Metric

The current Kp-index of 0.7 confirms a stable magnetosphere, ensuring no disruptions to satellite or electrical grid operations.

Geomagnetic activity is expected to stay at quiet levels, with the Kp-index forecast to remain below 2.0 throughout the next 24 hours. Radio propagation remains stable, and no significant space weather impacts are anticipated for satellite or ground-based operations.

🌌 Aurora Outlook

Aurora activity is currently restricted to high latitudes. Observers at mid-latitudes (40-60°N) should not expect any visible aurora displays given the current low geomagnetic levels.
