AB: On March 24, the THEMIS spacecraft were in a string-of-pearls configuration through the dusk plasma sheet at the recovery phase of a small storm. Large undulations of the plasma sheet were observed that brought the 5 probes from one lobe to another. Each neutral sheet crossing was accompanied by fast flows and Pi2 oscillations, which are the topic of a companion paper. In this paper we focus on the low frequency (~10min) large scale plasma sheet undulations and determine their propagation characteristics, origin, properties and their importance for the dynamic evolution of the tail in the presence of storm-time substorms.
