Geomagnetic activity is expected to remain low, with the Kp-index trending toward 1.0 over the next 24 hours.

more

No significant space weather disturbances are anticipated, as no major solar flares or coronal mass ejections are currently expected.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes.

more

Activity is confined to the highest polar latitudes, with no significant geomagnetic storms forecasted to push the auroral oval toward lower latitudes.

👁 Watch for

Monitor the development of Active Region AR4523, which currently shows the most complex magnetic configuration and the highest potential for further low-level flaring.
