Current geomagnetic conditions are quiet, but models forecast a shift to G2 storm levels early today. Elevated activity is expected to subside to unsettled levels by the second half of the day.

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.
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 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.
