The Earth’s magnetic field is currently quiet with a Kp-index of 2.0. Solar activity is being driven by five active regions, with AR4436 serving as the primary source of recent M-class flare activity. The F10.7 solar radio flux is at 142.0 sfu, indicating a moderate level of solar cycle energy but no immediate threat to terrestrial systems.

Key Metric

The current Kp-index of 2.0 confirms a lack of geomagnetic disturbance, ensuring nominal conditions for satellite operators and power grid stability.

Geomagnetic conditions are expected to remain at quiet levels, with the Kp-index likely dipping below 2.0 as the current minor disturbances subside. Expect background flare activity to continue at the C-class level, with a low 10% probability of further M-class events.

🌌 Aurora Outlook

Aurora activity is currently restricted to high-latitude regions near the poles. There is no significant visibility expected for mid-latitudes (40-60°N) during this period.
