Firstly, it was a gentle reminder that copyright extends to images as well as to the written word. Secondly, I'm not sure what you mean by the ""cracks" we see below the glowing layer of the phenumbral filaments." I see light colored lines crossing the area of the large sunspot, but those *are* filaments. Where am I supposed to be looking? As for the "flared aspect", all I see is a normal umbra inside a light, filamentary penumbra. Again, what am I supposed to be seeing? And no, this isn't meant to be snide, I'm honestly not seeing whatever it is you're looking at. If I can't see it, how can we discuss it?
