X-Ray
A/B (quiet)

Geomagnetic conditions are currently unsettled with a Kp-index of 3.0 following a slight uptick in solar wind activity. The sun remains quiet in terms of high-energy flares, maintaining nominal conditions for global infrastructure.

sfu · >150 = high activity

The planetary K-index has reached 3.0, indicating unsettled conditions, though there are no active geomagnetic storms. Five active regions are present on the solar disk, with an F10.7 flux of 151.0 sfu, reflecting a period of high background solar activity. X-ray flux remains at background levels, with only minor C-class activity detected in the last 12 hours.

Key Metric

The current Kp-index of 3.0 is the most important metric as it marks the threshold of unsettled conditions, requiring standard monitoring for satellite operators.

Geomagnetic activity is expected to subside over the next 24 hours as the solar wind influence wanes. Conditions will likely return to quiet levels by midday as the K-index trends downward toward 1.3.

🌌 Aurora Outlook

Aurora visibility remains confined to high-latitude regions. At the current Kp 3, there is little to no likelihood of mid-latitude auroral displays for observers between 40-60°N.
