The rocket investigation "Scattering Layer in the Bottomside Equatorial F-region Ionosphere", was part of the NASA EQUIS II
campaign. Two salvos of sounding rockets were launched from Roi Namur in Kwajalein on August 7th and 15th of 2004. The
project's mission was to investigate the thin scattering layers in the post sunset equatorial F region ionosphere that act as
precursors to a fully developed equatorial spread F. Each of the salvos consisted of one instrumented and two chemical
release payloads. The instrumented rockets were launched westward into equatorial spread F precursor that was first observed
from ground using the Altair radar. The instrumented rockets reached an apogee of ~450 km. The instruments consisted of a
Sweeping Langmuir Probe (SLP), a fixed bias DC Probe (DCP), a Plasma Impedance Probe consisting of a Plasma Frequency Probe
and a Plasma Sweeping Probe built at Utah State University. The instrument suite also included an Electric Field Probe built
by Penn State University. This poster presents observations of vehicle charging and preliminary data from the SLP and DCP.
