A/B (quiet)

Geomagnetic activity is currently subsiding following a period of minor unrest. The solar environment remains stable with no active storm conditions present.

F10.7 Solar Flux

sfu · >150 = high activity

The planetary K-index has dropped to 2.0, reflecting a calm magnetosphere. While the F10.7 flux remains at a elevated level of 153 sfu, signaling a healthy active sun, X-ray flux remains in the background A/B range. AR4485 remains the most notable feature, though its potential for significant eruptive activity has diminished as it rotates toward the western limb.

Key Metric

The current Kp-index of 2.0 indicates a stable geomagnetic field, meaning no near-term disruptions to power grids or satellite navigation systems.

Conditions are expected to remain quiet over the next 24 hours. The K-index is forecast to trend downward, settling below 2.0 by the latter half of the period.

🌌 Aurora Outlook

Aurora visibility is not expected at mid-latitudes. Observers should anticipate no significant auroral activity during this quiet interval.

Monitor AR4485 as it approaches the western limb; any late-stage eruptive activity there is unlikely to have a significant geoeffective impact on Earth.
