Experiments were performed to determine the stability characteristics of impulsive spin-down to rest in a circular cylinder of moderate aspect ratio. The characteristics measured include the onset time, onset wavelength, and time history of the wavelength for the Taylor-Görtler instability, as well as the global stability limit of the apparatus. Results compare favorably with earlier theoretical, numerical, and experimental investigations.
