Next 24 h
Geomagnetic conditions are expected to remain in the quiet-to-unsettled range over the next 24 hours. The Kp index is forecasted to rise to approximately 3.67 by late evening, reflecting a brief period of minor solar wind influence.
🌌 Aurora
Aurora visibility is not expected at mid-latitudes.

Observers at very high latitudes may see minor auroral activity, but conditions will be unfavorable for most stargazers.
👁 Watch for
Monitor the development of AR4518 and AR4520, as the 35% probability for M-class flares suggests a potential for sudden increases in X-ray flux.
