    QUIET

    Geomagnetic conditions are currently quiet with a Kp-index of 0.3. While the solar environment is calm, the high F10.7 radio flux indicates significant active region development on the solar disk.

    Next 24 h

    Geomagnetic conditions are expected to remain quiet through the next 24 hours, with Kp levels forecasted to stay below 2.0. The probability of C-class flares remains high at 90%, while M-class flare potential is notable at 55%.

    🌌 Aurora

    Aurora visibility is restricted to high-latitude regions, specifically near the poles.

    more

    Mid-latitude observers are unlikely to see any auroral activity under these current quiet conditions.

    👁 Watch for

    Monitor the evolution of AR4502 and AR4503, as their complex magnetic configurations currently present the highest potential for M-class flare activity.
