Next 24 h
Geomagnetic conditions are expected to remain quiet, with the K-index likely peaking at 3.0 during the next 24 hours. No significant solar radiation storms or radio blackouts are anticipated as solar flare probabilities remain low.
🌌 Aurora
Aurora visibility is restricted to high-latitude regions, generally within the auroral oval.
more
Mid-latitude observers should not expect any visible auroral activity during this period.
👁 Watch for
Monitor AR4551 for any evolution in magnetic complexity, as it is the most active region currently on the solar disk.
