Strong solar flare and CME
After days of suspenseful quiet, huge sunspot AR2665 finally erupted on July 14th (0209 UT), producing a powerful M2-class solar flare.
The explosion was underway for more than two hours and hurled a bright coronal mass ejection (CME) toward Earth.
Geomagnetic storms and high-latitude auroras are likely when the CME arrives this weekend.
