%X The propagation of elliptic Gaussian spatiotemporal incoherent beam in logarithmically saturable noninstantaneous nonlinear media is studied by using the mutual spectral density theory.The existing condition and the analytical expression of the beam radii and the coherence radii of spatiotemporal incoherent solitons are obtained.The initial condition of the beam and the nonlinearity of the media decide the propagation of the beam.It is find that the coherence properties of beam evolve periodically with the distance and the spatial correlation distance is smaller for higher frequency constituents of the incoherent light.
