    QUIET

    Solar activity is currently characterized by moderate flare production and unsettled geomagnetic conditions. While no significant storms are present, AR4494 remains the primary focus for potential M-class flare activity.

    Geomagnetic conditions are expected to remain in the quiet-to-unsettled range with Kp values oscillating between 2 and 3.33.

    Flare potential remains steady, with a 60% probability for M-class events originating from the current active regions as they rotate.

    🌌 Aurora

    Aurora visibility is not expected at mid-latitudes; activity will remain confined to high-latitude regions, likely providing minimal to no display for observers below 60 degrees latitude.

    👁 Watch for

    Monitor AR4494 for any signs of magnetic complexity growth that could elevate the risk of impulsive M-class solar flares.
