Scientific paper

Observations by IUE of the nova Aquila, announced on 27.85 Jan. 1982 UT, with visual magnitude of 6 to 7 are described. Observations made during 24 Feb. and 2 Mar. show that the nova has a heavily reddened spectrum, E(B-V) = 0.55 + or - 0.15, and a complex short wavelength spectrum with both narrow emission features and broad absorption troughs, indicating terminal velocities as high as 10,000 km/sec. Both the continuum flux and the absorption line profiles show complex changes between 24 Feb. and 2 Mar. On 24 Feb. short period variations were also present. Complementary optical, infrared and ultraviolet observations were obtained on 9 April.
