We observed the neutron star X-ray transient 2S 1803 - 245 in quiescence with the X-ray satellite XMM-Newton , but did not detect it .
An analysis of the X-ray bursts observed during the 1998 outburst of 2S 1803 - 245 gives an upper-limit to the distance of \leq 7.3 kpc , leading to an upper-limit on the quiescent 0.5-10 keV X-ray luminosity of \leq 2.8 \times 10 ^ { 32 } erg s ^ { -1 } ( 3 \sigma ) .
Since the expected orbital period of 2S 1803 - 245 is several hrs , this limit is not much higher than those observed for the quiescent black hole transients with similar orbital periods .
