UNSETTLED

Geomagnetic conditions are currently quiet, though the solar disk remains magnetically complex. Despite the calm Kp-index, the high probability of M-class flares necessitates continued monitoring for potential impulsive radio interference.

Next 24 h

Geomagnetic stability is expected to persist through the next 24 hours with the Kp-index hovering between 1.0 and 2.0. The primary activity will remain confined to solar flare production rather than geomagnetic storming.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes over the next 24 hours.

more

Observation should be limited to high-latitude polar regions where background auroral activity may be visible under clear, dark skies.

👁 Watch for

Monitor AR4498 and AR4499 for sudden magnetic evolution that could trigger impulsive X-ray emissions despite the lack of geomagnetic storming.
