Spectrophotometry of V711 Tauri

Spectrophotometric observations of the RS CVn binary system V711 Tau (HR 1099), convering the wavelength interval 3300–7100 Å, have been presented. A comparison of the standard spectral scans of V711 Tau with the spectral scans of the stars of known spectral types and luminosity classes taken from the Breger (1976) catalogue shows that, at all phases shown in the diagram, the spectral-luminosity type of the star is K0IV or K0III. The magnitude of the system fluctuates from 5^m.71 to 5^m.79 average being 5^m.75 approximately, the faintest being near 0^p.43 and the brightest near 0^p.78. The region around Balmer jump and near H region is apparently variable.
