The position of the recently found source IGR J17453-2853 as derived by INTEGRAL IBIS/ISGRI (see ATel #1005) is about 4 arcmin from that of Granat 1741.9-2853 (see ATel #1006; Muno et al. 2003, ApJ 598, 474). Formally, given the statistical 90% error regions of both sources (IGR J17453-2853: about 2 arcmin; Granat 1741.9-2853: about 1 arcsec), they can be regarded as two different sources. However, Granat 1741.9-2853 was found to be the only X-ray transient active in the near vicinity of IGR J17453-2853 by the Swift/XRT, about a day after the INTEGRAL observations (ATel #1006).
