We will present simulations of a highly localized, finite durationburst of 3D reconnection in a post-CME current sheet. Suchreconnection forms a pair of 3D reconnected flux tubes piercing thecurrent sheet. These tubes retract from the reconnection region,pushing their way through the surrounding magnetic field to form apost-reconnection arcade below the reconnection region. We willdiscuss how the evolution of these reconnected flux tubes can formthe descending, post-eruption voids which have been seen in thehigh corona by the Yohkoh, TRACE and LASCO instruments. Wewill compare the velocities and deceleration profiles of theobserved voids with those of the simulated reconnected flux tubes.We will also show how the presence of multiple reconnectionregions in a single current sheet affects the dynamics of thereconnected tubes.
