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

    Geomagnetic conditions are currently quiet with Kp levels residing at 2.3. The Sun exhibits moderate activity characterized by a consistent F10.7 flux of 157 sfu and low-level flare production.

    sfu · >150 = high activity

    The solar disk features five active regions, with AR4432 contributing the bulk of current C-class flare activity. X-ray flux remains firmly in the A/B background range, indicating no significant eruptive events are currently occurring. The planetary K-index has shown minor fluctuations but remains well below storm thresholds.

    Key Metric

    The F10.7 solar radio flux of 157 sfu serves as the primary indicator of high solar background activity, which supports healthy ionospheric conditions for radio communications.

    Expect geomagnetic conditions to persist at quiet to unsettled levels, with Kp trending down toward 2.0. Flare activity is expected to remain limited to occasional C-class events from existing active regions.

    🌌 Aurora Outlook

    Aurora visibility remains confined to high-latitude regions. No significant displays are anticipated for mid-latitudes under the current, quiet solar wind environment.
