We present XMM-Newton observations of the 569 sec period system RX J1914+24 ( V407 Vul ) .
This period is believed to represent the binary orbital period making it an ultra-compact binary system .
By comparing the phase of the rise to maximum X-ray flux at various epochs ( this includes observations made using ROSAT , ASCA and Chandra ) we find that the system is spinning up at a rate of 3.17 \pm 0.07 \times 10 ^ { -12 } s/s .
We find that the spectra softens as the X-ray flux declines towards the off-phase of the 569 sec period .
Further , the spectra are best fitted by an absorbed blackbody component together with a broad emission feature around 0.59keV .
This emission feature is most prominent at the peak of the on-phase .
We speculate on its origin .
