Solar X-ray
jets have flare-like properties but
clearly differ magnetically,
since they require an action in close proximity to very large-scale magnetic
fields that sometimes (if not usually) open out into the heliosphere itself.
The Archive contains other
related items, but this one explicitly introduces
twist.
Presumably this emanates from
geostrophic shear at the lower-left footpoint region, but then it is
physically confusing because the twist at the far end (lower right)
seems to be interfacing a photospheric region where curl(B) = 0. Maybe
this is possible in some dynamic sense.
