We report on the soft X-ray observations of the optically violent variable (OVV) quasar 3C 279, the first object of its class to be detected with the Gamma-Ray Observatory in GeV energies. We monitored 3C 279 in the winter of 1992/93 for abouth a month in radio to $\gamma$-ray frequencies. The soft X-ray observations, performed at least daily with the Position-Sensitive Proportional Counter aboard ROSAT satellite, covered the 0.2 - 2 keV X-ray band. The object was substantially fainter in X-rays than during several previous observations with Ginga , but nonetheless, it is possible to determine an accurate source flux and coarse spectrum form each orbit of data. In this presentation, we compare the flux history in X-rays to that measured in other wavelengths.
