The nucleus of the Seyfert galaxy NGC 4151 has been extensively monitored with the International Ultraviolet Explorer (IUE) in the wave- length range 1200–3000 A, a region of the spectrum where the contamination by the stellar component of the nuclear light is negligible. A first detailed account of the data collected from February 1978 to January 1979 is given in Penston et al (1981), and three more papers devoted to the continuum, the emission and the absorption lines based on all IUE data up to May 1980 are in preparation. This note is a summary of the paper on the continuum, which includes also optical and X-ray observations (Perola et al, 1981).
