Swift /XRT observations of the newly discovered INTEGRAL sources. Top: IGR J19173+0747. In this case only one soft X-ray source is found in Swift /XRT within the ISGRI error circle. We show on the right the 2MASS infrared image (J band) together with the Swift /XRT error circle and the position of the IR and optical counterpart. A positionally coincident ROSAT source is also shown. Bottom: for IGR J19294+1327 only one very faint soft X-ray excess has been found in the Swift /XRT observation (S/N = 3.7). Within the assumed XRT error circle there are two possible IR candidates, but no optical counterpart has been found (see the electronic version of the paper for the colored image).
