The galaxy is known to present kinematic evidence for a bysimmetric distortion, anyhow the stellar bar presence is controversial, due to the possible interpretation of NGC 2976 presenting an elliptical disk triggered by a prolate dark matter halo. We applied diagnostics in order to detect stellar bars or spiral arms. The m=2 fourier phase has a jump around 60 arcsecs consistent with a central bar and bisymmetric arms.
