Scientific paper

IUE low dispersion observations of the "jet" emission feature in the symbiotic variable R Aquarii were obtained over the course of two years. A comparison SWP λλ1200 - 2000 spectra obtained of both this feature and the central UV star indicates significant differences exist between these emission regions; Si III] λ1893 which is prominent in the central star is virtually absent in the "jet". Based upon analyses of UV and optical emission line spectra, the spectral properties of the feature suggest it is a highly excited tenuous region ≡104cm-3 characterized by prominent forbidden nebular line emission.
