V Sge is a short period, double-line spectroscopic and eclipsing close binary which is also intrinsically variable through a range of at most 3 mag in visual and photographic light. Almost all modern insight is founded upon the interpretation by Herbig, et al. (1965), who developed the evidence for the binary nature of the star, evaluated the nearly 0.5 day Keplerian period, studied the short-term Doppler and intensity variations of the spectrum, and obtained a limiting representation of the intrinsically noisy ultraviolet light curve. The orbital plane view of the binary, as developed by these authors, shows patchy distributions of 0 IIIf1 and 0 VI emissions and mass loss from the system as a whole.
