    X-Ray
    A/B (quiet)

    The Sun remains in a quiet, stable state with no significant geomagnetic disturbances occurring or expected in the next 24 hours. Current solar activity is moderate, characterized by low-level C-class flare production.

    Current geomagnetic conditions are quiet with a Kp-index of 2.7. The 10.7cm solar radio flux is at 126.0 sfu, indicating a steady, moderate level of solar output. With 11 active regions currently tracked, the overall environment is stable, and x-ray flux remains firmly within background levels.

    Key Metric

    The current Kp-index of 2.7 is the primary indicator of stability, confirming that the planetary magnetic field is currently undisturbed by solar wind activity.

    Geomagnetic activity is expected to remain quiet with the Kp-index oscillating between 0.67 and 2.0 throughout the next 24 hours. Solar flare potential remains dominated by low-level C-class events, with no immediate threat of significant radio blackouts or radiation storms.

    🌌 Aurora Outlook

    Aurora visibility is not expected at mid-latitudes. Activity is currently confined to higher latitudes, and without an increase in geomagnetic velocity or density, observers outside of the polar regions should not expect to see auroral displays.
