Spartan 201 is a shuttle deployed spacecraft that is scheduled to perf
orm ultraviolet spectroscopy and white light polarimetry of the extend
ed solar corona during two 40 hour missions to occur in September 1994
and August 1995. The spectroscopy is done with an ultraviolet coronal
spectrometer which measures the intensity and spectral line profile o
f HI Ly alpha up to heliocentric heights of 3.5 solar radii. It also m
easures the intensities of the OVI doublet at 1032 and 1037 Angstrom a
nd of Fe XII at 1242 Angstrom. The HI Ly alpha line profile measuremen
ts are used to determine the random velocity distribution of coronal p
rotons along the line-of-sight. The absolute HI Ly alpha intensities c
an be used together with electron densities from the white light coron
agraph to estimate electron temperatures from hydrogen ionization bala
nce calculations, and bulk outflow velocities from models of Doppler d
immed resonant scattering. Intensities of minor ion lines are used to
determine coronal abundances and outflow velocities of O5+. Ultraviole
t spectroscopy of extended coronal regions from the 11 April 1993 miss
ion of Spartan 201 are discussed.
