I'm surprised by this discovery too, I would have thought we would have been able to observe something like this with the STEREO spacecraft [0] which are pair of identical spacecraft that are imaging the sun at different angles.
“We demonstrate how apparently isolated loops could deceive observers, even when observations from multiple viewing angles are available”
I haven’t read it all yet and this topic is totally out of my wheelhouse, but it seems quite interesting.
> Contact with STEREO-B was lost in 2014 after entering an uncontrolled spin preventing its solar panels from generating enough power, but STEREO-A is still operational.
