Photograph of our closest star made using special calcium (CaK) band solar telescope.
In this special bandpass, which is on the border of visual spectrum and ultraviolet,
we can observe active regions within deep layer of chromsphere (deeper than h-alpha band) and white flocules which are creating large scale chromospheric network pattern around whole Sun.
Photo was made from many smaller tiles to achieve extraordinary resultion which are allowing you to study beautiful details of our closest star.
