Abstract
Absorption features in the IUE spectrum of the "hybrid" PG 1159-type centra l star of NGC 7094 have been identified and measured. We report equivalent widths for photospheric Fe vI and Fe vII features, interstellar and circums tellar absorptions, and variability of O v lambda 1371 and C Iv lambda 1549 P Cygni profiles. The terminal wind velocity of -3680 +/- 300 km s(-1) was determined from the high-dispersion C IV P Cyg feature. Some features from IUE and Hubble Space Telescope GHRS data are compared.
