    Geomagnetic activity is expected to remain quiet to unsettled, with Kp values oscillating between 2.6 and 3.0.

    Solar flare activity will likely remain dominated by low-level C-class events, with a moderate probability of M-class flares due to the complex nature of existing active regions.

    🌌 Aurora

    Aurora visibility for mid-latitudes is currently unlikely.

    more

    Observers at high latitudes (above 60°N) may experience brief, localized glows, but no major auroral displays are forecast for the next 24 hours.

    👁 Watch for

    Monitor active region AR4536 for potential magnetic evolution that could elevate the risk of an M-class solar flare.
