Quiet solar conditions with moderate flare probability
SOLAR: MODERATE
GEO: QUIET

Active Regions
8
X-Ray
A/B (quiet)

Solar activity remains in a calm state with geomagnetic conditions currently quiet at Kp 2.0. While active regions are numerous, they are demonstrating low flare production, indicating a stable environment for terrestrial infrastructure.

F10.7 Solar Flux
104.0
sfu · >150 = high activity

The solar disk hosts 14 active regions, yet X-ray flux remains at background levels with only minor C-class flares observed in the last 12 hours. The F10.7 index of 104 sfu confirms moderate levels of solar irradiance. The geomagnetic field is currently stable following a period of unsettled activity over the previous 48 hours.

Key Metric

The current Kp-index of 2.0 indicates a stable geomagnetic environment, meaning no significant disturbances to satellite operations or power grid stability are expected.

Geomagnetic activity is expected to briefly increase to Kp 3.67 as we transition through the next 24 hours, remaining within the G0 (none) category. Flare probability remains weighted toward C-class events, with only a marginal 5% chance for more significant X-class activity.

🌌 Aurora Outlook

Aurora visibility is not expected at mid-latitudes; activity will remain confined to high-latitude regions, potentially offering only faint displays near the poles.
