The cartoon

(click on the image for a larger version)

Here is a nice early cartoon that hints at the content of many more to come over the intervening decades: a current-carrying coronal filament interacts with a distinct open flux system, with presumably less twist, via magnetic reconnection. The unrequited twist (implying a suddenly incomplete current path) then launches a torsional Alfven wave into the coronal, entraining mass. In this early view, the flare (indicated by two ribbons) precedes this filament eruption.
