QUIET

Geomagnetic conditions are currently quiet, with the Kp-index fluctuating at low levels. Solar activity is stable despite a high F10.7 radio flux, indicating a robust but currently inactive solar disk.

Next 24 h

Geomagnetic activity is expected to remain quiet for the next 24 hours, with Kp values likely drifting between 1.0 and 1.7.

more

Solar flare activity will likely remain limited to occasional low-level C-class events, with no significant geomagnetic impacts anticipated.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes (40-60°N).

more

Observers at high latitudes may see only faint, localized activity, as geomagnetic conditions remain too subdued for broader displays.

👁 Watch for

Monitor the evolution of AR4508 as it rotates further onto the disk, as its complex magnetic classification may harbor potential for increased flare activity.
