To the possibility of a mobility edge in a random 1D lattice with   long-range correlated disorder
  Tight-binding 1D random system with long-range correlations is studied numerically using the localisation criterium, which represents the number of sites, covered by the wave function. At low degrees of disorder the signs of a mobility edge, predicted in \cite{Izr}, were found. The possibility of exact mobility edge in the system under consideration is discussed.
