Scientific paper

We present here preliminary results of BeppoSAX measurements of the prompt (2-700 keV) and afterglow (0.1 - 10 keV) emission of the `dark' GRB 001109. The burst light curves show indication of pulse broadening with the decrease of the energy band and its average spectrum is well described by the standard Band function from X to gamma-rays. The X-ray afterglow emission shows a monotonic power-law decay and its spectrum can be satisfactorily fitted with a photo-electrically absorbed power-law. Both the decay index and the photon index are inside the range of common values found in GRBs afterglows. More detailed data analysis and interpretation is in progress.
