    sfu · >150 = high activity

    The Sun currently hosts 11 active regions, characterized by moderate C-class flare production. Current X-ray flux is in the quiet A/B range, and the F10.7 index sits at 103 sfu, indicating a steady, moderate output of solar radiation. The Kp-index is hovering near 2.7, suggesting minimal immediate impact on terrestrial technology or navigation systems.

    Key Metric

    A Kp-index forecast of 3.67 indicates a trend toward unsettled geomagnetic conditions, though it remains below storm thresholds.

    Geomagnetic conditions are predicted to rise to Kp 3.67 by late this evening. This slight increase will likely persist through tomorrow, remaining well within the G0 (quiet) threshold with no expected major disruptions to power grids or satellite communications.

    🌌 Aurora Outlook

    Aurora visibility is not expected at mid-latitudes. Observers in far northern regions may see isolated, faint activity, but significant auroral displays are unlikely given current solar wind parameters.
