Вспышка класса М3 и выброс корональных масс 18 июня 2015 года

Attached is an updated video presentation capturing an M3.0 eruption and coronal mass ejection (CME) event on Thursday generated by big sunspot 2371. Although current tracking models differ, based on coronagraph imagery, the western edge of the full halo CME could deliver a glancing blow to our geomagnetic field by Sunday (June 21). Sky watchers at high latitudes should be alert for visual aurora displays should local weather and light conditions allow. More updates regarding this to follow when necessary.
