How to create a solar flare

I've searched high and low on google to find a tutorial on how to create a solar flare but none exists. I'm now at a deadend and need guidance on how to create it. There are plenty of tutorials on flames, but they look like fire rather than a flare. Firstly the flames have a central point from which they burn, secondly they have layers of flames and thirdly the edges of flames are nice and smooth. Solar flares have a loop effect on them (look at the real sun pictures to see this), the flares have suttle shades of differences within each layer and finally the flares are diffused at the edges and sharp as well (both effects need to be present but random and heading in the same direction as the flare loop is headed - so the side of the loop has flares emanating from the side while the top of the loop has flares emanating to the top). As a beginner I'm struglling to piece together different small learnings together to create the effect, can anyone help with this?
