    The planetary K-index is at a quiet level of 2.0, indicating stable geomagnetic conditions. Solar flux (F10.7) is measured at 118 sfu, reflecting moderate solar cycle activity, and current X-ray flux is limited to background A and B levels. With three identified active regions, activity is present but currently lacks the magnetic complexity required for significant flaring events.

    Key Metric

    The F10.7 solar flux of 118 sfu indicates the sun is maintaining moderate activity levels, providing a steady baseline for satellite drag and ionospheric conditions.

    Geomagnetic conditions will remain at quiet levels, with the K-index expected to oscillate between 1.5 and 3.0 throughout the next 24 hours. No significant solar radiation storms or radio blackouts are forecast, as flare potential remains low at 20% for M-class events.

    🌌 Aurora Outlook

    Aurora visibility is not expected for mid-latitudes (40-60°N). Observers should anticipate standard, non-event conditions with activity largely confined to high-latitude polar regions.

    Monitor AR4465 and AR4470 for any sudden increases in magnetic complexity, which could raise the probability of M-class solar flares.
