Geomagnetic conditions are expected to remain quiet with Kp levels hovering between 2.0 and 2.3 through the next 24 hours. No significant space weather disturbances are anticipated, and the probability of M-class flares remains low at 10%.

🌌 Aurora

Aurora activity is currently restricted to high-latitude polar regions.

Mid-latitude observers should not expect visible displays under current conditions.

👁 Watch for

Monitor the evolution of AR4524 and AR4529, as their magnetic complexity could shift, potentially increasing the likelihood of localized C-class flare activity.
