Density evolution of in-falling prominence material from the 7th June 2011 CME

This work investigates the density of in-falling prominence material following the 7 ^th June 2011 eruption. Both the evolution and the distribution of the density is analysed in five discreet ``blobs'' of material. The density appears to be remarkably uniform, both spatially within the blobs, and temporally over the course of the descent of each, although a slight concentration of material towards the leading edge is noted in some cases.
