Active Regions
4
X-Ray
A/B (quiet)

Geomagnetic conditions remain quiet with a Kp-index of 1.0, reflecting a stable solar wind environment. Solar activity is currently marked by low-level flare probability despite the presence of 25 active regions.

F10.7 Solar Flux
140.0
sfu · >150 = high activity

The Earth’s magnetic field is currently undisturbed, with the Kp-index holding steady at 1.0. An F10.7 flux of 140 sfu indicates moderate solar activity levels, sufficient to maintain steady ionospheric conditions for satellite operations and radio communications. No solar radiation storms or radio blackouts are currently detected.

Key Metric

The current Kp-index of 1.0 indicates a lack of solar wind driving, ensuring stable conditions for global radio and satellite navigation systems.

Expect geomagnetic conditions to remain at quiet levels, with the Kp-index projected to stay near 1.67 throughout the next 24 hours. While there is an 80% probability of C-class solar flares, no significant disruptions to ground-based infrastructure or satellite systems are anticipated.

🌌 Aurora Outlook

Aurora activity is expected to be minimal. Visual sightings at mid-latitudes are highly unlikely, as geomagnetic activity is well below the threshold required to drive auroral displays toward lower latitudes.
