  We present the results of the analysis of GRB 101023 in the fireshell
scenario. Its redshift has not been determined due to the lack of data in the
optical band, so we tried to infer it from the Amati Relation, obtaining z=0.9.
Its light curve presents a double emission, which makes it very similar to the
already studied GRB 091018. We performed a time-resolved spectral analysis with
XSPEC using different spectral models, and fitted the light curve with the
numerical code GRBsim. We used Fermi GBM data to build the light curve, in
particular the second INa detector, in the range (8-440 keV). We found that the
first emission does not match the requirements for a GRB, while the second part
perfectly agrees with being a canonical GRB, with a P-GRB lasting 4s.
