While no statistically significant large-scale anisotropy is found on the celestial sphere, some small-scale anisotropy -- clustering of cosmic rays -- is observed. Above 4 x 10$^{19}$eV, there are one triplet and six doublets within separation angle of 2.5$^{\circ}$ and the probability of observing these clusters by a chance coincidence under an isotropic distribution is now order of 10$^{-3}$. The self-correlation separation angle distribution shows a sharp peak within 2.5$^{\circ}$, which is consistent with the angular resolution of the AGASA experiment. So, the clusters of AGASA events look like point-sources.
