Solar activity is currently stable, but a transient disturbance is expected to push geomagnetic conditions into G2 (moderate) storm levels later today. Expect a brief period of increased activity before returning to quiet conditions.
⚠ Kp 4 expected · 4 more below
Geomagnetic activity is forecast to rise to Kp 5.67 (G2 storm) around 21:00 UTC on October 11. Conditions are expected to moderate rapidly, returning to Kp 3.0 shortly after midnight.
Mid-latitude observers should prepare for potential aurora visibility during the evening hours of October 11 as the geomagnetic disturbance arrives.

Optimal viewing will be between 21:00 UTC and midnight, specifically at high northern latitudes.
