    The sun is exhibiting quiet behavior across all NOAA space weather scales. The F10.7 index is at 104.0 sfu, indicating moderate radio output. Five distinct active regions are currently visible, though their magnetic configurations are not currently conducive to major eruptive events, resulting in only minor C-class flare activity over the past 24 hours.

    Key Metric

    The 40% probability for M-class flares is the primary metric to monitor, as any significant eruption could shift the geomagnetic outlook rapidly.

    Geomagnetic activity is expected to trend downward toward Kp 2.0 as current minor instabilities subside. No significant solar radiation or radio blackout events are anticipated, though there remains a 40% chance for an M-class flare given the active regions currently rotating across the disk.

    🌌 Aurora Outlook

    Aurora visibility remains limited to high-latitude regions, such as the Arctic Circle. Conditions are not favorable for mid-latitude sightings in the next 24 hours.
