Solar Astrophysics afficionados may be familiar with videos showing moving images of highly active Coronal displays featuring jetting sunspots. This type of Sunspot is generally imaged close to the solar surface and appears to be the source of either a CME (Coronal Mass Ejection) or a Solar Flare. A search ofor this type of image will reveal that a proportion of these jetting sunspots eject flares and local core materiel that does not follow ballistic laws.
The jets ejecta trajectory, one would assume, would follow a ballistic curve , such as those that are associated with ballistic missiles, or artillery shell trajectories. They arch upwards and follow a ballistic curve down to the surface.
What transpires here is that the ejecta/plasma jet does indeed follow a ballistic trajectory, but only as far as the appogee (highest point) of the balistic arc. As the jet approaches the appogee, the velocity
degrades to zero and the ejecta is then rapidly drawn rapidly back to source.
This suggests that this type of jetting body, ie. the sunspot, ie. a solar flare or CME sunspot, is in effect a Solar Mascon(mass concentration) that does not possess the capability to jet at escape velocity but is capable of recapturing its own ejecta, from thousands of miles above the corona. Such a sunspot would of course possess twin jets where the downward projecting jet would be jetting into the solar interior.
