QUIET

Current solar conditions are unsettled with a Kp-index hovering around 3.3. While geomagnetic activity is currently stable, six active regions remain on the solar disk, keeping the potential for moderate flares elevated.

Expect the geomagnetic field to fluctuate between quiet and unsettled levels through the next 24 hours, with Kp values peaking near 3.67.

Flare risk remains notable, with a 75% probability of M-class activity, though no major earth-directed eruptions are currently in progress.

🌌 Aurora

Aurora activity is expected to remain limited to high latitudes.

more

Observers at mid-latitudes are unlikely to see significant displays, as current conditions do not support widespread equatorward displacement of the auroral oval.

👁 Watch for

Monitor the M-class flare probability closely, as any sudden X-ray flux increase could indicate a developing active region that may impact satellite communications or shortwave radio bands.
