We present an improved measurement of the Rossiter-McLaughlin effect for theexoplanetary system HD 17156, based on radial-velocity data gathered with theSubaru 8.2m telescope throughout the planetary transit of UT 2008 November 7.The data allow for a precise and independent determination of the projectedspin-orbit angle of this system: $\lambda = 10.0^{\circ} \pm 5.1^{\circ}$. Thisresult supersedes the previous claim of $\lambda = 62^{\circ} \pm 25^{\circ}$by Narita et al., which was based on lower-precision data with poor statistics.Thus the stellar spin and planetary orbital axes of the HD 17156 system arelikely to be well-aligned, despite the planet's large orbital eccentricitysuggesting a history of strong dynamical interactions.
