    sfu · >150 = high activity

    Current solar activity is moderate with a 10.7cm flux of 114 sfu and eight active regions across the disk. Two M-class flares originated from AR4475 earlier today, confirming the region’s potential for further eruptions. The planetary K-index has risen to 3.3, reflecting the ongoing response to recent solar wind enhancements.

    Key Metric

    The Kp-index of 4.67 represents the most immediate impact, as it indicates a transient period of G1 geomagnetic activity capable of inducing minor power grid fluctuations and satellite orientation adjustments.

    Geomagnetic activity is expected to peak at Kp 4.67 (G1 level) around 21:00 UTC today before subsiding to quiet levels by early tomorrow. Solar flare probabilities remain weighted toward C-class events, with a 25% chance of further M-class activity over the next 24 hours.

    🌌 Aurora Outlook

    Auroral activity is expected to be limited to high latitudes. Observers at mid-latitudes are unlikely to see displays, though those in northernmost regions should monitor local conditions during the brief peak at 21:00 UTC.

    Monitor AR4475 for additional M-class flares, as its current configuration remains the primary source of instability in the solar atmosphere.
