    The Sun shows 7 active regions, but magnetic complexity remains low, resulting in a quiet R0 radio environment. F10.7 solar flux is holding at 144 sfu, indicating moderate solar cycle activity. Current geomagnetic conditions are unsettled but well within normal parameters, with no significant impacts on terrestrial infrastructure.

    Key Metric

    The Kp index of 3.0 indicates current unsettled geomagnetic conditions, though it remains below storm thresholds.

    Expect the K-index to oscillate between 2.0 and 3.67 over the next 24 hours. No significant geomagnetic or radiation storms are anticipated during this period as the solar wind environment remains nominal.

    🌌 Aurora Outlook

    Aurora visibility for mid-latitudes remains low. Observers in northern-most regions may see minor activity, but there is no expectation of geomagnetic storming that would extend auroral displays further south.
