    QUIET

    Solar activity remains at very low levels with planetary geomagnetic conditions currently quiet at Kp 0.7. No significant space weather disturbances are anticipated over the next 24 hours.

    Conditions are expected to remain quiet with Kp indices hovering between 1 and 3. No solar radiation storms or radio blackouts are forecast as flare probabilities remain negligible for M and X-class events.

    🌌 Aurora

    Aurora activity is currently restricted to high latitudes.

    more

    Observers in mid-latitudes (40-60°N) should not expect any visible auroral displays under the current stable conditions.

    👁 Watch for

    Monitor the magnetic evolution of AR4551 as it transits toward the solar limb; while currently quiet, any sudden increase in magnetic complexity could shift the flare probability.
