ACTIVE

Geomagnetic conditions are currently active due to recent solar flare output, with G1 storm levels expected to persist into the near term. The sun remains active as AR4549 continues to produce M-class flare activity.

Solar flare risk remains elevated, with a 60% probability of further C-class events and a 10% chance of additional M-class activity.

🌌 Aurora

Aurora visibility is restricted to higher latitudes; observers in Canada and Scandinavia may catch glimpses as the Kp index pushes toward 4-5.

more

Mid-latitudes (40-60°N) are unlikely to see significant displays under current conditions.

👁 Watch for

Monitor AR4549 for further M-class flare emissions as it continues its transit toward the solar limb, which may trigger additional geomagnetic disturbances.
