Geomagnetic conditions are expected to remain quiet for the next 24 hours, with Kp levels likely fluctuating between 1 and 3.

more

No significant solar radiation or radio blackouts are anticipated, maintaining a stable environment for global communications and navigation systems.

🌌 Aurora

Aurora visibility for mid-latitudes (40-60°N) is not expected within the next 24 hours.

more

Observers should not anticipate significant auroral displays, as current conditions are insufficient to drive widespread light shows.

👁 Watch for

Monitor the development of active regions for any sudden increase in magnetic complexity or impulsive flare activity that could disrupt the current period of stability.
