Active Regions
2
X-Ray
A/B (quiet)

The sun is currently in a period of quiet geomagnetic activity with planetary indices well below storm thresholds. Solar activity remains moderate, characterized by routine C-class flare production.

F10.7 Solar Flux

sfu · >150 = high activity

The planetary K-index is currently 0.7, indicating stable conditions for satellite operations and power grid stability. With an F10.7 flux of 131.0 sfu, the solar atmosphere is moderately active, though recent GOES X-ray monitoring shows no significant flare events beyond minor C-class activity. No significant space weather threats are present at this time.

Key Metric

The current Kp-index of 0.7 confirms a stable geomagnetic environment, indicating no immediate risk of space weather-induced technical disruptions.

Expect geomagnetic conditions to remain quiet, with Kp values projected to stay below 2.0 throughout the next 24 hours. No significant perturbations to the magnetosphere are anticipated.

🌌 Aurora Outlook

Aurora visibility is not expected for mid-latitudes. The current conditions are only conducive to auroral displays at very high polar latitudes.
