Imaging ARs 2391 and 2392, I found an interesting feature--what looks like a meandering river of white hot fire (just above and beginning right of center in the image below). Many times the size of earth, this feature is a flow of plasma following twisted magnetic fields on the sun. Imaged with PST-DS and ASI 120MM. Stacked in Registax 6 with unsharp mask, cropping and colorizing in Photoshop.
Below is a view of a larger portion of the sun's disk. The imaged area is close to the disk center.
