    Next 24 h

    Geomagnetic conditions are expected to remain quiet for the next 24 hours, with the Kp index likely to hover near or below 2.0. Solar flare activity will continue at low levels, with a 75% chance of minor C-class events.

    🌌 Aurora

    Aurora activity is currently restricted to high latitudes.

    more

    Observers at mid-latitudes should not expect visibility, as current solar wind conditions are insufficient to drive auroral displays toward the equator.

    👁 Watch for

    Monitor the evolution of active region AR4536 as it approaches the western solar limb, as sudden morphological changes could indicate a potential for minor flare eruptions.
