During the storm the plasmapause moved to <jats:italic>L</jats:italic> < 2.5 and at least one density notch and drainage plume formed. These features were evident in all the data sets for some days. One notch extended from 2.4–4.5 R<jats:sub><jats:italic>E</jats:italic></jats:sub> and spanned <4 hours in MLT. Plume mass and electron densities were enhanced by a factor of about 3.
