Quiet geomagnetic conditions persist with moderate solar flux levels
SOLAR: MODERATE

Active Regions
5
X-Ray
A/B (quiet)

Solar activity remains at baseline levels with no significant geomagnetic disturbance. While multiple active regions are present, they are currently characterized by low-level flare potential.

sfu · >150 = high activity

The planetary K-index is holding steady at 1.0, reflecting a magnetically quiet environment for Earth. Solar flux is currently 129.0 sfu, indicating moderate solar activity, though recent flare production has been restricted to minor C-class events. With 8 active regions identified, the solar disk remains physically active but currently lacks the magnetic complexity required for larger eruptive events.

Key Metric

The current F10.7 flux of 129.0 sfu indicates a robust, healthy solar cycle, providing sufficient background ionization for satellite orbital drag monitoring.

Geomagnetic conditions are expected to remain quiet for the next 24 hours, with Kp levels likely peaking near 2.67 by early tomorrow. No significant solar radiation or radio blackouts are anticipated as current regional magnetic configurations appear stable.

🌌 Aurora Outlook

Aurora visibility is not expected at mid-latitudes (40-60°N). Observers in high-latitude regions may see only faint, localized activity consistent with nominal solar wind conditions.
