Resumen:
We present a large scale anisotropy study using the East-West method applied to the events detected by the inll array with energies above 10**16 eV (using data collected until 30 April of 2011). No signicant signal of a dipolar modulation in right ascension is found and thus a 99 % CL upper limit for the dipole component in the equatorial direction is derived. The observed phases of the rst harmonic in right ascension for energies between 10**16 eV and 10**18 eV is compatible with a constant value of  Phi = (247 +/- 25), which is close to the right ascension of the Galactic Center. The results are consistent with those obtained with the main array in the overlapping energy range.
