Description
We report the discovery of a previously unnoticed X-ray source with a periodic variability at 614.28s. Its spectrum is an absorbed 1.8keV-blackbody with an iron-line feature. It has a Lx about $1.2\times10^{34}\times$(D/10 kpc)$^{2}$ erg s$^{-1}$ and has no obvious optical counterpart(fx/fo larger than 1600). We argue it is most likely a neutron-star ultra-compact X-ray binary with the shortest orbital period so far.
