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

Solar activity remains at low levels with no significant geomagnetic disturbances expected in the next 24 hours. The solar environment is currently characterized by stable, quiet conditions.

sfu · >150 = high activity

The planetary K-index is holding steady at 0.7, reflecting a tranquil magnetosphere. Solar flux is currently at 140 sfu, suggesting a moderate, stable background radiation level. With 27 active regions present but exhibiting minimal flare potential, the sun is currently quiet in both X-ray and geomagnetic terms.

Key Metric

The current Kp-index of 0.7 indicates minimal geomagnetic perturbation, ensuring no operational impact on power grids or satellite communications.

Geomagnetic conditions are expected to remain at Kp 2 or lower through the next 24 hours. No significant space weather events or disturbances are anticipated for Earth’s orbital environment.

🌌 Aurora Outlook

Aurora visibility is restricted to high-latitude polar regions; there is no expected impact for mid-latitude observers at this time.
