  Coronal jets, which extend from the solar surface to beyond 2 $R_\odot$, were
observed in the polar coronal hole regions during the total solar eclipse on
2017 August 21. In a time-series of white-light images of the corona spanning
70 minutes taken with our multi-site observations of this eclipse, six jets
were found as narrow structures upwardly ejected with the apparent speed of
about 450 km s$^{-1}$ in polar plumes. On the other hand, extreme-ultraviolet
(EUV) images taken with the Atmospheric Image Assembly of the Solar Dynamics
Observatory show that all of the eclipse jets were preceded by EUV jets.
Conversely, all the EUV jets whose brightness is comparable to ordinary soft
X-ray jets and which occurred in the polar regions near the eclipse period were
observed as eclipse jets. These results suggest that ordinary polar jets
generally reach high altitudes and escape from the Sun as part of the solar
wind.
