Abstract (from CDS):

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 500keV. GRB 021125 lasted ∼24s with a mean flux of ∼5.0photons/cm²/s in the 20-500keV energy band, and a fluence of ∼4.8x10^–5erg/cm2 in the same energy band. Here we report the analysis of the data from the imager IBIS and the spectrometer SPI.
