Geomagnetic activity at G1-G2 levels following solar wind arrival
SOLAR: MODERATE

A/B (quiet)

Earth is currently experiencing G1 to G2 geomagnetic storming as the magnetosphere reacts to an influx of solar wind. Conditions are expected to gradually subside throughout the day as the disturbance moves past Earth’s orbit.

Planetary Kp-Index

0–9 scale · ≥5 = geomagnetic storm

F10.7 Solar Flux
137.0
sfu · >150 = high activity

The planetary K-index sits at 5.0, reflecting moderate geomagnetic activity. Solar activity remains moderate with an F10.7 flux of 137 sfu and low-level C-class flaring originating from the current roster of 34 active regions. Satellite and radio infrastructure remains within nominal operating parameters, showing no signs of high-energy radiation degradation.

Key Metric

The current Kp-index of 5.0 is the primary metric, signaling that Earth’s magnetic field is actively responding to ongoing solar wind coupling.

Geomagnetic activity is projected to remain at G1 levels briefly before decaying toward quiet conditions by midday UTC. No significant flare activity above M-class is anticipated, though minor C-class events will likely continue as solar regions rotate across the disk.

🌌 Aurora Outlook

Observers at high latitudes may still witness auroral displays as the storm settles. Mid-latitude sightings are unlikely under current levels, though clear, dark skies at northern locations (55°N+) may provide faint visibility for a few hours post-dawn.
