Next 24 h
Geomagnetic conditions are expected to settle further, with Kp levels dropping to 2.0 or below within the next 6 to 9 hours. No significant solar flaring or radiation threats are anticipated over the next 24-hour window.
🌌 Aurora
Aurora visibility is not expected at mid-latitudes (40-60°N).
more
Observers in the high-latitude regions may see minimal, localized activity, but nothing that would extend into lower latitudes.
👁 Watch for
Monitor AR4551 for any unexpected magnetic complexity, although current flare probabilities remain very low.
