Solar activity remains low with high-probability M-class flare potential
SOLAR: MODERATE
GEO: QUIET

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

Current solar conditions are quiet, with global geomagnetic indices remaining stable at low levels. Despite the lack of significant geomagnetic activity, there is a heightened probability of moderate solar flares due to the magnetic complexity of active regions.

F10.7 Solar Flux

sfu · >150 = high activity

The planetary K-index sits at 2.7, indicating a quiet magnetosphere. Solar activity is currently characterized by a steady F10.7 flux of 100 sfu and background X-ray emission at the A/B level. With 32 active regions currently identified, there is a persistent, if moderate, potential for localized energetic events.

Key Metric

A 70% probability of M-class flares suggests that while the current state is quiet, the potential for sudden radio propagation disturbances remains a notable risk for short-wave communication.

Geomagnetic conditions are expected to remain quiet for the next 24 hours, with Kp values projected to stay below 2.0. The solar environment will likely see continued C-class flare activity, with a 70% chance of an M-class flare as AR4446 and AR4447 evolve.

🌌 Aurora Outlook

Aurora visibility is not expected at mid-latitudes (40-60°N). Observers should anticipate little to no auroral activity, as the current solar wind conditions are insufficient to drive widespread displays.
