Next 24 h
Geomagnetic conditions are expected to oscillate between unsettled and active states over the next 24 hours. The Kp index is forecasted to remain near the threshold of G1 storm levels, tapering off slightly by the early…
🌌 Aurora
Observers at higher mid-latitudes (near 55-60°N) may have opportunities to view aurora activity if clear skies persist.
👁 Watch for
Monitor the magnetic orientation (Bz component) of the incoming solar wind; a sustained southward shift could potentially push current activity levels into the…
