“The Sun unleashed an M-2 (medium-sized) solar flare with a substantial coronal mass ejection (CME) on June 7 that is visually spectacular.
The large cloud of particles mushroomed up and fell back down looking as if it covered an area of almost half the solar surface.” – YouTube
While the flare is not massive in and of itself (it is only an M-2, after all), the solar storm accompanying the flare is really what puts it in a spectacular category.
The sun has been very quiet for a long while now, so this is certainly welcome, in a sense, by the NASA scientists.
