Peculiar velocities distort the correlation function of galaxies in redshift space. In the linear regime, the distortion has a characteristic quadrupole plus hexadecapole form, with amplitude depending on the cosmological density parameter {OMEGA}. I report here measurements of the anisotropy of the correlation function in the IRAS 2 Jy redshift survey. The inferred value of {OMEGA} is {OMEGA} = 0.5^+0.5^_-0.25_.
