QUIET

Current solar activity is characterized by a quiet geomagnetic field and minimal flare production. The Sun’s output remains within expected ranges for the current cycle phase.

⚠ Kp 4 expected · 4 more below
Next 24 h

Geomagnetic conditions are expected to remain quiet with the Kp index likely staying below 2.5. No significant solar radiation storms or radio blackouts are anticipated, as flare probabilities for M and X-class events remain very low.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes.

Observers located at high latitudes may see minor, baseline auroral activity, but conditions are currently unfavorable for significant displays.

👁 Watch for

Monitor AR4551 for any structural evolution that might increase its potential for producing further C-class or M-class solar flares over the next 24 hours.
