    Geomagnetic conditions are currently unsettled with a Kp-index of 3.3, though no significant storms are observed. Solar flare activity remains characterized by frequent C-class events, with an elevated 55% probability for M-class flares over the next 24 hours.

    F10.7 Solar Flux

    sfu · >150 = high activity

    The Sun is displaying moderate activity with 8 active regions currently monitored across the disk. The F10.7 solar radio flux is at 124.0 sfu, indicating a moderate level of solar output. While flare production is consistent, it remains confined to the C-class range, resulting in no significant impact on Earth’s magnetosphere or ionosphere at this time.

    Key Metric

    The 55% probability for M-class flares is the primary metric, as these events can cause localized radio degradation on the sunlit side of Earth.

    Expect geomagnetic conditions to briefly reach Kp 4 within the next few hours before trending downward toward quieter levels. Flare activity will likely persist at the C-class level, with a continuing 15% risk for an X-class eruption from complex magnetic regions.

    🌌 Aurora Outlook

    Auroral activity is expected to remain limited. Observers at high latitudes (above 60°N) may see minor activity during the Kp 4 interval, but mid-latitude observers should not expect visible displays.
