Abstract
Low resolution observations of the elliptical galaxy NGC 1052 have been obtained with both the long and short wavelength cameras of the IUE satellite. These have been combined with optical multi-aperture photometry to demonstrate a low reddening of EB–V ∼ 0.06. There is no evidence for a compact source of non-thermal radiation capable of ionizing sufficient gas to radiate the observed Balmer line flux. The strongest UV emission lines are O II] λ 2326 and C III] λ 1909, a situation similar to that in the Cygnus loop supernova remnant. The energy distribution of NGC 1052, if typical, implies important revisions to the K-corrections for high redshift galaxies.Keywords
