The analysis of the data of the COMPTON observatory [BATSE Burst catal
og] indicates the existence of dipole asymmetry with amplitude a=0.036
in the direction b=-22-degrees, l=30-degrees. The observational data
are shown to agree qualitatively with the giant dark matter halo (GDMH
) model of Gurevich et al. [Phys. Lett. A 175 (1993) 397]. The method
of observational verification of the GDHM model is suggested.
