Solar activity remains low with quiet geomagnetic conditions
SOLAR: MODERATE
GEO: QUIET

Active Regions
6
X-Ray
A/B (quiet)

Solar activity is currently low, with the geomagnetic field remaining quiet. While ten active regions are present on the disk, overall flare production remains confined to minor C-class events.

F10.7 Solar Flux
99.0
sfu · >150 = high activity

The planetary K-index sits at a stable 2.0, reflecting a quiet magnetosphere with no significant solar wind disturbances. The F10.7 solar radio flux is holding steady near 99 sfu, consistent with current levels of solar cycle activity. Solar flare output is minimal, characterized by isolated C-class events, with no immediate threats to satellite operations or power grids.

Key Metric

The current F10.7 flux of 99.0 sfu indicates a baseline level of solar activity that maintains standard ionospheric conditions for radio communications.

Geomagnetic conditions are expected to remain quiet for the next 24 hours, with Kp levels hovering between 1 and 2. While there is a 55% probability of M-class flares due to the presence of multiple active regions, no significant space weather impacts are anticipated for Earth-based infrastructure.

🌌 Aurora Outlook

Aurora activity is expected to be limited to high-latitude regions, particularly near the poles. Observers at mid-latitudes (40-60°N) should not expect visible auroral displays at current activity levels.
