    X-Ray
    A/B (quiet)

    Current solar activity is characterized by a moderate F10.7 flux of 122 sfu and stable, quiet geomagnetic conditions. While minor fluctuations in the K-index are expected today, no significant storming is currently underway.

    F10.7 Solar Flux

    sfu · >150 = high activity

    The Sun is currently in a state of low-to-moderate activity with five active regions observed across the disk. X-ray flux remains quiet, dominated by low-level C-class flare potential. The planetary K-index is holding steady at 2.0, indicating a tranquil magnetosphere.

    Key Metric

    The F10.7 radio flux at 122 sfu is the key indicator, reflecting a moderate level of solar activity that supports stable radio propagation for satellite and high-frequency communication operators.

    Geomagnetic activity is expected to trend briefly toward unsettled levels with a peak Kp of 3.67 occurring within the next few hours. Conditions will settle back to quiet levels by the latter half of the 24-hour period.

    🌌 Aurora Outlook

    Aurora visibility is not expected at mid-latitudes. Observers in high-latitude regions may see minimal, quiet-time auroral activity consistent with a Kp of 3-4.
