During the HRTS-9 flight, spectrograms and spectroheliograms where obtained of the quiet sun, quiet limb, plage, and
sunspots. Previous analysis of these observations required the correction of a small set of spectra for instrumental
distortions and the absolute intensity calibration. We have applied these corrections to a larger portion of the HRTS-9
observations where the spectrograph slit was rastered across a small region of the sun along the solar equator. This set of
corrected spectrograms has allowed us to generate high spatial and spectral resolution spectroheliograms of the observed
quiet and active portions of the sun. In addition, with use of a magnetogram taken while the flight was in progress we have
examined the relationship between the photospheric magnetic field and both Mg II emission at 280 nm and absorption features
in the nearby solar spectrum due to both neutral and singly ionized species. In this presentation we will present our high
resolution spectroheliograms as well as results showing the relationship between the magnetic field and several specific
spectral features.
