Geomagnetic activity is expected to rise sharply to Kp 5.67 (G2 storm) early in the cycle before tapering off to Kp 4.0 by mid-day. We anticipate continued moderate-level flaring, with a 20% probability of a significant X-class event.

🌌 Aurora

Observers at mid-latitudes (40-60°N) should prepare for potential displays during the initial G2 storm window early today.

Visibility will be limited to northern horizons as the storm intensity wanes throughout the afternoon.

👁 Watch for

Watch for the transition from the anticipated G2 storm peak back to baseline, as the rate of decline in the K-index will dictate the duration of possible auroral activity.
