F10.7 Solar Flux

sfu · >150 = high activity

The Sun is exhibiting moderate activity levels with an F10.7 flux of 135 sfu, driven by 28 active regions across the disk. Geomagnetic conditions are quiet with a current Kp index of 2.3. X-ray flux remains at background levels, with only minor C-class flare activity observed in the past 12 hours.

Key Metric

The current Kp-index of 2.3 confirms that the geomagnetic field is undisturbed, meaning no space weather impacts are expected for power grids or satellite navigation.

The Kp index is expected to remain between 1.5 and 2.0 through the next 24 hours, indicating continued quiet geomagnetic conditions. While there is a 90% probability of C-class solar flares, no significant impact on Earth’s ionosphere or satellite operations is projected.

🌌 Aurora Outlook

Aurora activity will be limited to high-latitude regions near the poles. Mid-latitude observers should not expect visible auroral displays at this time.
