Abstract	V630 Cas is one of several long-period cataclysmic variables with rare,long-duration, dwarf nova outbursts. The characteristics of these outbursts arelikely shaped by the large physical size of the accretion disks. Moreover, theyoften are luminous (> 10e33 ergs/s) X-ray sources in quiescence, severelychallenging the disk instability model. Here we propose an XMM-Newtonobservation of V630 Cas in quiescence to constrain the white dwarf mass and theaccretion rate, possibly adding it to the list of troubling systems with a highaccretion rate white dwarf with a large, quiescent accretion disk. We alsopropose to obtain fast UV photometry with the OM, since UV flickering is a keydiagnostic of accretion for the related class of symbiotic stars.

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.
