Next 24 h

Geomagnetic conditions are expected to remain quiet through the next 24 hours, with Kp levels likely to hover below 2.0. No significant solar flares or major space weather events are anticipated.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes due to current quiet geomagnetic conditions.

Observers should anticipate no significant auroral displays outside of the typical high-latitude polar regions.

👁 Watch for

Monitor the evolution of AR4523 and AR4521 as they rotate further onto the visible disk, as these regions have the potential for increased flare activity in the coming days.
