Solar activity remains stable with high F10.7 flux and quiet geomagnetic levels.
SOLAR: MODERATE
GEO: QUIET

Active Regions
5
X-Ray
A/B (quiet)

Current solar conditions are quiet with the geomagnetic field remaining undisturbed. Solar activity is characterized by a steady F10.7 radio flux of 151 sfu, suggesting moderate solar cycle progression despite a lack of eruptive events.

F10.7 Solar Flux
151.0
sfu · >150 = high activity

The planetary K-index is currently 0.3, indicating very stable conditions for satellite and ground-based infrastructure. With 28 active regions present, the solar disk is well-populated, although current X-ray flux remains at background A and B levels. The recent trend shows a consistent decline in geomagnetic activity over the past 24 hours.

Key Metric

The F10.7 solar radio flux of 151 sfu is the most important metric, as it indicates a high level of atmospheric ionization, which impacts satellite drag and long-range radio propagation.

Geomagnetic conditions are expected to remain in the quiet range, with the Kp index likely peaking at 2.67 in the next few hours before settling. No significant solar radiation storms or radio blackouts are anticipated, as M-class and X-class flare probabilities remain low.

🌌 Aurora Outlook

Aurora visibility is restricted to high-latitude polar regions. Mid-latitude observers should not expect any significant auroral displays during this period.
