Polarized, stored beams are becoming a more and more important tool in nuclear and high-energy physics. In order to measure the beam polarization in a storage ring the polarization vector of the stored beam has to aim, revolution for revolution, over a period of seconds to minutes, into the same, so-called stable direction. In this paper measurements at the Indiana University Cooler Ring are described in which for the first time in a storage ring, oscillations around this stable direction have been measured. The existence and the dynamics of such oscillations are, for instance, important for a new proposed technique for polarizing stored hadron beams.
