Photograph of Sun made using special h-alpha (H-a) band solar telescope.
In 2022 we are able to observe growing activity of our closest star – on
this photograph – made in very narrow bandpass (around hydrogen emission line)
we are able to see spectacular active regions, prominences and small
chromosphere details presented with extraoddinary resolution.
