Query: WISEA J064750.85-154616.4: a new nearby L/T transition dwarf   Aims: Our aim is to detect and classify previously overlooked brown dwarfs in
the solar neighbourhood. Methods: We performed a proper motion search among
bright sources observed with the Wide-field Infrared Survey Explorer (WISE)
that are also seen in the Two Micron All Sky Survey (2MASS). Our candidates
appear according to their red $J$$-$$K_s$ colours as nearby late-L dwarf
candidates. Low-resolution near-infrared (NIR) classification spectroscopy in
the $HK$ band allowed us to get spectroscopic distance and tangential velocity
estimates. Results: We have discovered a new L9.5 dwarf, WISEA
J064750.85-154616.4, at a spectroscopic distance of about 14 pc and with a
tangential velocity of about 11 km/s, typical of the Galactic thin disc
population. We have confirmed another recently found L/T transition object at
about 10 pc, WISEA J140533.13+835030.7, which we classified as L8 (NIR).
