Abstract	We are proposing for the last of 6 XMM-Newton 15ks observations of the dM+WDpre-cataclysmic variable QS Vir in a coordinated joint HST-XMM campaign. Threeyear multi-cycle joint HST-XMM observations were approved in 2014, but XMMlacked a multi-cycle program to follow the 2nd and 3rd year HST approval. HSTdata probe the accretion rate of the M dwarf wind through WD photosphericabsorption lines, while XMM measures accretion through accretion shock emission.Earlier non-coordinated observations showed different accretion rates by afactor of 1000. The new observation will probe the accretion variability overthe crucial year timescale, provide a measure of the variability of the M dwarfmass and angular momentum loss rates, and make a key test of accretion rates derived from different techniques.

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.
