Abstract
Recent localizations of cosmic gamma-ray bursts (GBRs) are studied taking into account the estimations of their intensities. The increase of the avergage intensity of GRBs along galactic longitudesl=220–260° andl=40–80° is found. It may be associated with the Orion spiral arm and the central region of the Galaxy. Corresponding enhancement of the number of intense GRBs for directions along the Orion arm is also found. Astrophysical conclusions from this possible galaxy-scale distribution of GRBs are discussed.
