Latest alerts

G1 - Minor geomagnetic storm (Kp 5+) - High latitude sky watchers have a chance to see visual aurora. The higher middle latitudes might see aurora on the northern or southern horizon, depending on which hemisphere you are located.
Moderate M2.21 solar flare from sunspot region 12403
G2 - Moderate geomagnetic storm (Kp 6) - High latitude sky watchers have a high chance to see visual aurora. The higher middle latitudes have a good chance to see visible aurora on the northern or southern horizon, depending on which hemisphere you are located. There is also a slight chance for weak aurora on the horizon at the lower middle latitudes but the chances are still low.
