    UNSETTLED

    Geomagnetic activity is currently elevated at Kp 4 but is trending downward. The solar environment remains stable with no immediate threat of significant X-ray bursts or geomagnetic storms.

    Geomagnetic conditions are forecast to calm to quiet levels as the current disturbance passes. C-class flare activity remains possible due to the existing number of active regions, but the likelihood of M-class or X-class events is low.

    🌌 Aurora

    Aurora visibility is restricted to high-latitude regions.

    more

    Observers in mid-latitudes are unlikely to see displays, as the Kp index is forecast to fall below the threshold for mid-latitude visibility within the next few hours.

    👁 Watch for

    Monitor the development of AR4536, the most complex region currently on the disk, for any sudden changes in magnetic configuration.
