    X-Ray
    A/B (quiet)

    Solar activity is currently low with the Kp-index hovering at quiet levels of 2.7. No significant geomagnetic or radiation storms are observed, and conditions remain stable across the Earth’s environment.

    F10.7 Solar Flux

    sfu · >150 = high activity

    The sun is currently in a quiet state, characterized by low-level C-class flare activity and a moderate F10.7 flux of 106 sfu. With 11 active regions present on the visible disk, the solar surface is complex, but the lack of impulsive eruptive events maintains a calm space weather environment. Satellite operations and radio communications are currently unaffected by solar emissions.

    Key Metric

    The 50% probability of M-class flares is the most important metric, as it indicates potential for localized radio interference if an impulsive event occurs.

    Geomagnetic activity is expected to remain in the quiet range, with the Kp-index likely to settle near 2.0 within the next 24 hours. While there is a 50% probability of M-class flares due to the number of active regions, no major disturbances are currently forecasted.

    🌌 Aurora Outlook

    Aurora visibility is restricted to high-latitude regions, particularly near the poles. Mid-latitude observers should not expect significant auroral displays under these stable conditions.

    Monitor AR4455 as it rotates into a more central position, as its magnetic complexity may influence flare productivity over the coming 24 hours.
