QUIET

Solar activity is currently stable with background conditions prevailing across the space environment. While magnetic activity remains present in active regions, the geomagnetic field is quiet with no significant storming expected.

Next 24 h

Geomagnetic conditions are expected to remain quiet for the next 24 hours. The K-index may see minor, transient increases toward Kp 3, but no geomagnetic storming is forecasted for the Earth-directed environment.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes during this period.

more

Activity will remain largely restricted to high-latitude regions, providing minimal opportunity for observers in the 40-60 degree bands.

👁 Watch for

Monitor the development of Active Region AR4513 as it rotates further into view, as its magnetic complexity may influence flare productivity over the next 24 hours.
