S Per. Temporal behaviour for five prominent outbursting features at 1667 MHz with central velocities at a)  −52.9 km s^-1; b)  −54.1 km s^-1; c)  −55.4 km s^-1; d)  −55.3 km s^-1; e)  −56.9 km s^-1. For each feature from the bottom to top panels are shown the drifts in velocity, Stokes I flux, Stokes V flux, degree of circular polarization m_C, linearly polarized flux p, degree of linear polarization m_L, and polarization PA.
