    ☀ HELIOS SOLAR WATCH · 2026-06-26 16:00 UTC
    Solar activity remains stable with moderate background flux levels
    SOLAR: MODERATE
    GEO: QUIET

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

    Geomagnetic conditions are currently quiet with a Kp-index of 2.3, though solar activity remains elevated due to the presence of nine active regions. The sun is currently in a state of moderate background flux, typical for this phase of the cycle.

    F10.7 Solar Flux
    117.0
    sfu · >150 = high activity

    The solar environment is stable, characterized by an F10.7 flux of 117.0 sfu and quiet X-ray background levels. Nine active regions are currently visible on the solar disk, with AR4478 showing potential for further C-class flare production. No significant geomagnetic disturbances are impacting Earth’s magnetosphere at this time.

    Key Metric

    The current F10.7 solar radio flux of 117.0 sfu indicates a healthy, moderate level of solar output that supports high-frequency radio propagation but does not pose a threat to infrastructure.

    Expect geomagnetic conditions to hover between unsettled and quiet, with Kp levels likely reaching 3.0 throughout the next 24 hours. Flare activity will likely remain limited to minor C-class events, with a low 5% probability of a significant X-class flare.

    🌌 Aurora Outlook

    Aurora activity is expected to remain restricted to high latitudes. Observers at mid-latitudes should not expect visible displays under current conditions.

    Monitor AR4478, located at S06E49, for any sudden increase in magnetic complexity that could raise the probability of M-class solar flares.
