Abstract :
In the late afternoon of November 25th, 2002 a gamma-ray burst (GRB) was detected in the partially coded field of view (about 7.3° from the centre) of the imager IBIS on board the INTEGRAL satellite. The instruments on-board INTEGRAL allowed, for the first time, the observation of the prompt gamma-ray emission over a broad energy band from 15 to 500 keV. GRB 021125 lasted ~24 s with a mean flux of ~5.0 photons cm ^-2 s^ -1 in the 20-500 keV energy band, and a fluence of ~ 4.8* 10^5 erg cm^-2 in the same energy band. Here we report the analysis of the data from the imager IBIS and the spectrometer SPI.
