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

The solar environment is currently quiet with no significant geomagnetic disturbances reported. Activity levels are moderate, characterized by low-level flare production and stable solar flux.

F10.7 Solar Flux

sfu · >150 = high activity

The planetary K-index is holding steady at 1.3, reflecting a calm magnetosphere. Solar flux (F10.7) is measured at 114.0 sfu, sitting well within the moderate range for the current cycle. While eight active regions are present on the disk, overall X-ray output remains at background A/B levels, indicating a lack of high-energy eruptive activity.

Key Metric

The current F10.7 flux of 114.0 sfu is the most important metric, as it indicates a sustained, moderate level of activity that supports high-frequency radio propagation without the risk of storm-related disruptions.

Geomagnetic conditions are expected to remain quiet with the Kp-index hovering between 0.6 and 1.7 over the next 24 hours. No significant space weather impacts are anticipated for power grids, satellites, or radio communications.

🌌 Aurora Outlook

Aurora visibility for mid-latitudes (40-60°N) is effectively zero under these current quiet conditions. Observers should not expect any auroral activity outside of the immediate polar regions.

Monitor the complexity of active regions AR4473 and AR4475, as their magnetic configuration (BG) carries a non-zero probability for M-class flare activity.
