    sfu · >150 = high activity

    The planetary K-index has subsided to 3.7 after a minor uptick, indicating a return to stable conditions. Solar flux is holding steady at 103 sfu, consistent with the moderate flare activity observed. X-ray output remains low, with only minor C-class events reported in the last 12 hours.

    Key Metric

    The F10.7 solar flux of 103.0 sfu provides a baseline for ongoing moderate solar activity and atmospheric ionization levels.

    Geomagnetic activity is expected to remain low over the next 24 hours, with Kp values likely staying below 3.0. No significant geomagnetic storms are anticipated during this period.

    🌌 Aurora Outlook

    Aurora activity will be limited to typical high-latitude regions. Observers at mid-latitudes are unlikely to see significant displays given current K-index projections.
