X-Ray
A/B (quiet)

Solar activity is currently stable with geomagnetic conditions remaining at quiet levels. Despite a high solar radio flux of 157 sfu, flare productivity remains restricted to low-level C-class events.

F10.7 Solar Flux
157.0
sfu · >150 = high activity

The sun is currently quiet with six active regions contributing to a steady F10.7 flux of 157 sfu, indicating a robust solar cycle phase. X-ray flux is holding in the A/B range, reflecting minimal impulsive activity. Current Kp-index readings are at a nominal 1.3, suggesting no immediate geomagnetic disturbances affecting Earth’s magnetosphere.

Key Metric

The F10.7 flux of 157 sfu is the key indicator, confirming that despite the lack of storms, the solar atmosphere remains energetic and well-primed for potential activity.

Expect stable geomagnetic conditions for the next 24 hours, with the Kp-index peaking briefly at 3.0 before settling back to quieter levels. Solar flare activity will likely remain dominated by small C-class events from active region AR4432.

🌌 Aurora Outlook

Aurora visibility is not expected at mid-latitudes (40-60°N). Observers should anticipate only standard high-latitude auroral activity consistent with quiet geomagnetic conditions.
