    QUIET

    The Sun is currently in a quiet state, with solar activity dominated by minor C-class flare production. Geomagnetic conditions are currently stable and expected to remain at low levels over the next 24 hours.

    The Kp-index is expected to see a slight, temporary uptick to 3.67 around 06:00 UTC before subsiding back to quiet levels of 1.0 by midday.

    more

    No significant solar radiation storms or radio blackouts are anticipated, as X-ray flux remains at low B-class background levels.

    🌌 Aurora

    Aurora visibility is not expected for mid-latitudes.

    more

    Observers should not anticipate significant displays, as geomagnetic activity is insufficient to push the auroral oval south of high polar latitudes.

    👁 Watch for

    Monitor the development of AR4560 as it rotates toward the western limb, as its magnetic complexity (Eai/BG) warrants continued observation for potential C-class flare growth.
