The High Resolution Fly's Eye (HiRes) experiment is a stereo air fluorescence detector for the study of cosmic rays with energies above 10~(18) eV.When a cosmic ray-induced air shower is seen by both detectors,the reconstruction of the cosmic ray arrival direction has a typical uncertainty on the order of 0.5deg.This makes HiRes well suited for anisotropy studies.We present here an analysis of the distribution of ultra-high energy cosmic ray arrival directions observed in stereo by the HiRes experiment.In particular,we search for anisotropies in the distribution on small scales (< 5deg) and at the highest energies (> 10~(19) eV),where the prospects for identifying point sources seem most promising.
