The T Tauri-type star RU Lupi was observed in X-ray, UV, optical, IR, and radio spectral ranges from 1983 to 1986. Strong variations in different time-scales are detected in all the wavelength regions, in the line intensities, and in continuum. The UV spectrum shows strong similarities with those of other T Tauri-type stars, with the exception of the presence of He II (1640 A) variable emission line. The optical spectrum shows generally lower variations than the UV one. The Balmer and He I lines are quite constant. Strong variations are present in the IR behavior of RU Lupi, in particular P alpha and Br beta are sometimes in emission and others in absorption.
