	abstract = {We report the results of AstroSat and NuSTAR observations of the Be/X-ray binary pulsar SXP 15.3 in the Small Magellanic Cloud during its outburst in late 2017, when the source reached a luminosity level of \~{}10<SUP>38</SUP> erg s<SUP>-1</SUP>, close to the Eddington limit. The unprecedented broad-band coverage of the source allowed us to perform timing and spectral analysis between 3 and 80 keV. The pulse profile exhibits a significant energy dependence, and morphs from a double-peaked profile to a single broad pulse at energies >15 keV. This can be explained by a spectral hardening during an intensity dip seen between the two peaks of the pulse profile. We detect a Cyclotron Resonance Scattering Feature at \~{}5 keV in the X-ray spectrum, independent of the choice of the continuum model. This indicates a magnetic field strength of 6 {\texttimes} 10<SUP>11</SUP> G for the neutron star.},
