Ion saturation current and floating potential fluctuations are recorded by movable array of 4 Langmuir probes near
 the boundary of the confinement region in the l = 3/m = 9 Uragan-3M torsatron with an RF produced and heated
 plasma. On the basis of these data main spectral and time characteristics of the low frequency electrostatic turbulence
 have been derived. The existence of the radial electric field shear and reversal of poloidal phase velocity of the
 fluctuations at the plasma boundary have been confirmed. The time function of the turbulent E×B particle flux contains
 intermittent bursts with the amplitude multiply exceeding the average flux. Up to 70% of the total fluctuating flux is
 carried in these bursts.
