    QUIET

    Solar activity is currently stable, characterized by a moderate F10.7 flux and a rise in geomagnetic activity to Kp 3. The sun remains quiet in terms of explosive events, with no significant X-ray flare activity detected.

    Expect geomagnetic conditions to hover between Kp 1 and 3 over the next 24 hours.

    more

    The probability of C-class solar flares remains at 60%, suggesting continued minor activity from the existing active regions, while more significant flare events are unlikely.

    🌌 Aurora

    Aurora visibility is not expected at mid-latitudes.

    more

    Observers at very high latitudes may see minor activity, but there is no forecast for significant displays at this time.

    👁 Watch for

    Monitor the five active regions for any signs of magnetic flux emergence that could increase the probability of M-class solar flares.
