    Next 24 h

    Conditions are expected to remain quiet with minor, transient increases in geomagnetic activity as the Kp index reaches an estimated 3.33 later today.

    more

    No significant solar radiation or radio blackouts are forecast, allowing for stable operations across all satellite and radio sectors.

    🌌 Aurora

    Aurora visibility is not expected at mid-latitudes.

    more

    Observers in high-latitude regions may see minor, localized auroral activity, but conditions are not conducive to significant displays.

    👁 Watch for

    Monitor the development of AR4530 and AR4529, as their magnetic complexity could evolve into minor C-class flare activity.
