  We present the timing and spectral studies of RX J0209.6-7427 during its rare
2019 outburst using observations with the Soft X-ray Telescope (SXT) and Large
Area X-ray Proportional Counter (LAXPC) instruments on the AstroSat satellite.
Pulsations having a periodicity of 9.29 s were detected for the first time by
the NICER mission in the 0.2-10 keV energy band and, as reported here, by
AstroSat over a broad energy band covering 0.3-80 keV. The pulsar exhibits a
rapid spin-up during the outburst. Energy resolved folded pulse profiles are
generated in several energy bands in 3-80 keV. To the best of our knowledge
this is the first report of the timing and spectral characteristics of this Be
binary pulsar in hard X-rays. There is suggestion of evolution of the pulse
profile with energy. The energy spectrum of the pulsar is determined and from
the best fit spectral values, the X-ray luminosity of RX J0209.6-7427 is
inferred to be ${1.6}\times 10^{39}$ ergs s$^{-1}$. Our timing and spectral
studies suggest that this source has features of an ultraluminous X-ray pulsar
in the Magellanic Bridge. Details of the results are presented and discussed in
terms of the current ideas.
