Scientific paper

Existing IUE and Einstein observations of the high-redshift (z = 1.414) quasar 3C 446 have been analyzed. In the UV the continuum is characterized by a steep slope. The lack of signal shortward of 2300 Å is probably due to the Lyman continuum absorption at the source. The X-ray spectrum shows the "universal" slope of active galactic nuclei coupled with a hydrogen columnar density in excess of the Galactic value, suggesting that the absorption occurs in or around the source.
