A well-executed cartoon showing before-and-after views of a filament allegedly being triggered into a confined eruption by emerging flux. The paper uses high-resolution ground-based observations, as well as SDO and STEREO, on SOL2019-05-09, and liberally appeal to CSHKP concepts.
This cartoon is a good example of how one's intuitive view of coronal currents may differ. The twist in the filament prior most likely reflects a non-neutralized current linking two patches of the vertical component of curl(B) in the solar interior. It seems highly implausible that this interface could change suddenly, with deep-seated field stress switching off simultaneously. Other nice cartoons in this Archive, for example that of Sturrock show similar signs of artistic license apparently violating physical laws.
