This paper presents a preliminary study of the IUE UV spectrum of the planetary nebula NGC 40. Details of the observations are given in Table 1 which were obtained in the low resolution (Δλ ∼ 6å) spectrophotometric mode using both SWP (λλ1150–2000) and LWR (λλ1850–3250) spectrographs. All data were acquired using the large (10′x20′) apertures. SWP3076 was taken with the centre of the aperture offset by 7′.5N of the central star: all other images were obtained with the slot centred on the nucleus.
