AB: During the the SMEI mission, Ulysses has been at relatively low latitudes (less than 25 degrees) and near aphelion (4.8 to 5.4 AU). This has provided us with an opportunity to trace interplanetary transient disturbances from near the Sun (with LASCO), around 1AU with SMEI and ACE and then again near 5AU with Ulysses. We have selected a number of events where the identification of the disturbance is clear in LASCO, SMEI and Ulysses and use the propagation of the disturbance through the heliosphere to draw conclusions regarding the dynamics of these disturbances. In particular we focus on the duration of the "driving flow" and on the significance of "swept-up" matter.
