We propose for a joint observation of SSvirgulCyg in its optical quiescence andoutburst states with NuSTAR and XMM with the aim of having first robustdetection of reflection component, commonly observed in binaries and AGNs.Presence of such component have been inferred via detection of Fe 6.4 keVline, however no direct detection till date. We will fit the phase averagedspectra to derive reflection amplitude. These measurements will help verifytheoretical ideas like presence of central hole in disk, main contributingsite for the reflection during the two states and also to study response ofthe system to varying accretion conditions.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
