sfu · >150 = high activity

The solar disk hosts 8 active regions with a total of 12 active spots, maintaining an F10.7 flux of 124.0 sfu. X-ray flux is currently in the background A/B range, indicating no immediate radio disruption to Earth’s ionosphere. Recent minor geomagnetic fluctuations have subsided, leaving the planetary K-index in a calm state.

Key Metric

The M-class flare probability of 55% is the primary metric to track, as it suggests sufficient complexity in current active regions to trigger localized space weather events.

Geomagnetic activity is expected to remain largely quiet, with a slight uptick to Kp 3.0 forecast for late UTC hours today. Flare probabilities are stable, with a 55% chance of M-class events due to the magnetic complexity within the active regions.

🌌 Aurora Outlook

Aurora visibility is not expected at mid-latitudes (40-60°N) within the next 24 hours. Observers in high-latitude regions may see minor activity, but generally, conditions remain unfavorable for significant displays.
