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.
