A long slit spectrum from the barred galaxy NGC 1415 has been obtained withthe 2.1m Guillermo Haro telescope in Cananea, Mexico at position angle 155d(EofN) and shows the kinematics of Na I D lines (in absorption) and Halpha,6562.8 A, [NII] 6548 A, [NII] 6584 A, [SII] 6716 A, and [SII] 6731 A lines inemission from the central regions and the disk. Our previous Halphacontinuum-free imaging of the central region showed mainly two central brightHalpha knots straddling the nucleus, and Halpha emission regions along thesouth-east and north-west inner spiral arms. Velocities of the Na I Dabsorption lines are taken as representative of the rotation curve of NGC 1415.Our kinematical data indicates that the central bright Halpha straddling thenucleus have velocities in excess of the Na I D velocities. We interpret thesevelocity excesses of the central bright Halpha knots as due to a geyser(nuclear bipolar outflow) with V_outflow 140 km/s at a P.A.+165d (EofN). Theaxis of this outflow, is not along the rotation axis of the disk of NGC 1415(if it were, it would be at P.A.+238d (EofN)). Additionally we have determinedOmega_{gas}, (radial resonances) kappa(R) and estimated the value of thepattern angular speed of an inner boxy stellar bar in NGC 1415, Omega_{bar},from the Na I D rotation curve assuming Ratio of CR/a_{bar} = 1, Omega_{bar} =134 km/s.
