    QUIET

    Geomagnetic conditions are currently quiet, though solar activity remains elevated due to recurring M-class flare production from active region AR4513. The solar environment is stable for Earth-based systems, but flaring potential warrants continued monitoring.

    Geomagnetic conditions are expected to remain quiet with Kp levels steady at 1.67 over the next 24 hours.

    The probability of additional C-class flares remains high at 90%, with a continued 40% chance of further M-class activity originating from AR4513.

    🌌 Aurora

    Aurora activity is expected to be confined to high-latitude regions.

    more

    There is no significant geomagnetic disturbance forecast, so mid-latitude observers should not expect visible auroral displays at this time.

    👁 Watch for

    Monitor AR4513 for any evolution in magnetic complexity, as this region remains the primary source for flare activity.
