    X-Ray
    A/B (quiet)

    Current solar activity is quiet with stable geomagnetic conditions holding at Kp 0.7. Solar output remains within expected ranges for this phase of the cycle with no significant space weather disturbances currently detected.

    F10.7 Solar Flux
    121.0
    sfu · >150 = high activity

    The sun is exhibiting low-level activity across four active regions, with the F10.7 flux holding steady at 121 sfu. X-ray flux remains in the A/B range, indicating no significant flare activity, and the global geomagnetic field remains undisturbed. This quiet state provides ideal conditions for satellite operations and radio communications.

    Key Metric

    The F10.7 flux of 121 sfu indicates a moderate level of solar radio emissions, which provides a consistent baseline for atmospheric density and ionospheric conditions.

    Geomagnetic conditions are expected to remain stable, with Kp levels hovering near 2.0 through the next 24 hours. There is a moderate probability of C-class flares, but major eruptive events are unlikely at this time.

    🌌 Aurora Outlook

    Aurora activity is expected to be minimal, limited to high-latitude regions. Observers at mid-latitudes should not expect visible displays given the current low Kp values.

    Monitor the magnetic complexity of AR4420 and AR4419; while currently quiet, their Beta-Gamma classifications possess the potential for isolated flare development.
