We describe the velocity structure of the curved outflow S187:SCP 1 (H2). Observations of the 2.12 μm molecular hydrogen emission were obtained using an IR Fabry-Pérot interferometer with a spectral resolution of 24 km s-1 and a spatial resolution of 1.6''. The covered region of 3.6 ' × 3.6' contains the entire curved-jet and several H2 nebulosities, such as the counter-jet candidate, SCP 3 and SCP 4. The kinematics show that the curved jet is centered around a radial velocity of -30 km s-1 with velocity components spanning 40 km s-1. On the other hand, knots SCP 3 and 4 and the counter-jet candidate appear red-shifted at velocities -12 to 30 km s-1. We discuss whether the observed velocity structure favors the side-wind model or precession interpretations of the jet curvature.
