Observations by the INTEGRAL space observatory on 25-26 October 2013 and 30-31 October 2013 of the Small Magellanic Cloud & Bridge detected a previously uncatalogued bright X-ray source. The source is much brighter in the first observation than the second and is seen in both the IBIS and the JEM-X instruments. A peak flux of approximately 4mCrab was detected in both IBIS and JEM-X detectors in the 20-40 keV range. This implies a luminosity of approximately 1 x 10^37 erg/s at the SMC distance. The best location of the source from the first observation using the JEM-X camera is 00 56 57, -72 25 52 (2000) with an uncertainty of 1.5 arcmins â hence we assign the name IGR J00569-7226 to this object. Follow-up XMM-Newton observations have been triggered to locate the object more precisely. From the behaviour of the source, and its location in the Bar of the SMC, this is likely to be a new High Mass X-ray Binary system.
