Solar Orbiter observations strongly connect a switchback with an active solar region and support formation near the Sun through magnetic reconnection. They do not definitively settle the origin of switchbacks as a class: competing work still considers solar-wind formation and finds the evidence compatible with more than one mechanism.
Two lenses on the same evidence. Source weight and the primary source ratio show what each rests on.

The dissenting position does not reject Solar Orbiter’s observation; it challenges the stronger conclusion that the observation definitively identifies the origin of all switchbacks. Models and statistical analyses retain solar-wind formation as a possibility. Some studies report that switchback rates do not vary with distance from the Sun as expected under a simple near-Sun source model, while other work finds multiple mechanisms plausible.
The origin remains debated because theories place the source either near the solar transition region or in the solar wind itself.
A Parker Solar Probe analysis reported that the hourly averaged switchback rate was independent of distance from the Sun, a result used to distinguish competing source theories.
Numerical modelling shows lower-atmosphere processes can form switchbacks, but it also notes that the simulated structures may not enter the solar wind, limiting the conclusion.
An assessment of coronal jets describes lower-coronal reconnection as a likely seed, while allowing direct or indirect generation and emphasizing that the origin remains under debate.
