We propose a 20 ks observation of the source CXOU J204734.8+300105 at the centreof FOV during XMM-Newton AO-16 cycle. With Chandra observation, this source wasproposed as a Polar having orbital period of virgul6097 sec and showing clear eclipse(Israel et al. 2016). In XMM-Newton observation of the Cygnus Loop, for whichthis source is at the edge does not show the same characteristics and instead itshows modulations at shorter period of 237 sec and having lower luminosity. Boththese observations show different results. We would like to have a 20 ksobservation of this source which may give a much more insight to the sourcewhich will help to establish its true nature and able to study its variability.We will perform detailed timing and spectral analysis of this source.

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.
