Whatever they show it's very interesting, thanks for sharing.

Yup, the images show different spectrum's ... I think its the dark shadow in the middle that might not normally have been seen before this way, but then again there is no cause for alarm or concern on the NASA site they originate from, so perhaps its just a new photography technique that highlights the core of the sun in a darker way or shadow?

But yes, great pics by the OP.
