  A small blowout jet was observed at the boundary of the south polar coronal
hole on 2011 February 8 at around 21:00 UT. Images from the Atmospheric Imaging
Assembly (AIA) on board the Solar Dynamics Observatory (SDO) revealed an
expanding loop rising from one footpoint of a compact, bipolar bright point.
Magnetograms from the Helioseismic Magnetic Imager (HMI) on board SDO showed
that the jet was triggered by the cancelation of a parasitic positive polarity
feature near the negative pole of the bright point. The jet emission was
present for 25 mins and it extended 30 Mm from the bright point. Spectra from
the EUV Imaging Spectrometer on board Hinode yielded a temperature and density
of 1.6 MK and 0.9-1.7 x 10^8 cm^-3 for the ejected plasma. Line-of-sight
velocities reached up to 250 km/s and were found to increase with height,
suggesting plasma acceleration within the body of the jet. Evidence was found
for twisting motions within the jet based on variations of the LOS velocities
across the jet width. The derived angular speed was in the range 9-12 x 10^-3
rad s^-1, consistent with previous measurements from jets. The density of the
bright point was 7.6 x 10^8 cm^-3, and the peak of the bright point's emission
measure occurred at 1.3 MK, with no plasma above 3 MK.
