Solar jets are transient, collimated flows of plasma in the Sun's atmosphere.
The plasma ejected by a solar jet travels away from the Sun along straight or oblique paths, tracing the local magnetic field.
Due to the wide range of temperatures and regions of the solar atmosphere in which jet-like phenomena are observed, solar jets are referred to by many different names.
Since ejected plasma from a single event may have a wide range of temperatures, any one event may be referred to by one or more names depending on the waveband or wavebands observed.
Furthermore, some solar jets are classified as macrospicules due to their similarities with the much smaller chromospheric spicules.
