patial and temporal structure of Alfvén waves was studied with array of magnetic probes in compact tokamak TUMAN-3M. Poloidal mode numbers have been determined for Alfven instabilities bursts of the two types: short and long ones. Absence of poloidal rotation of magnetic field perturbations was found for both types of bursts. Also, in both cases, no pronounced asymmetry of magnetic field perturbation in the direction of the major radius was detected.
