Scientific paper

The paper presents photometric, spectroscopic, and spectrophotometric observations of H2252-035 over the wavelength range 1200-22,000 A made in 1980. The continuum is well represented by a blackbody of 12,500 K over most of this range. The infrared points (JHK) show evidence for a slightly cooler contribution. There is a significant excess at wavelengths less than 2200 A. It is argued that the optical flux does not come from reprocessing in the atmosphere of the secondary star, but that most of the optical flux comes from an accretion disc in the system, with the 859-s modulation coming from the bright-spot region.
