QUIET

Current solar conditions are quiet with the planetary K-index holding at 1.0. Solar activity remains moderate, characterized by occasional C-class flaring from existing sunspot regions.

Geomagnetic conditions are expected to remain quiet to unsettled, with Kp indices likely to stay below 3.0. No significant geomagnetic storms are anticipated, and solar flare activity will likely be limited to occasional C-class events.

🌌 Aurora

Aurora visibility for mid-latitudes (40-60°N) is not expected in the next 24 hours.

Observers should remain alert for potential high-latitude auroral displays, but low to mid-latitude skywatchers will see minimal activity.

👁 Watch for

Monitor the development of AR4520 and AR4518, as any sudden increase in magnetic complexity could shift the probability of M-class solar flares higher.
