In all cases, the XRT position confirms a previous association with 3 AGNs (Masetti et al., 2006, A&A, 459, 21; Kuiper et al., 2006, Atel 684). In the following we report the results of these measurements IGR J14175-4641 The XRT observation locates the source at RA(J2000) = 14h17m03.8s and Dec(J2000) = -46d41m39.7s, with an error box of 10 arcsec, thus confirming the association with the Seyfert 2 galaxy LEDA 511869 at z = 0.076; the source is too weak to allow spectral analysis, but the 2-10 keV XRT flux of 5.8 x 10<SUP>-14</SUP> erg cm<SUP>-2</SUP> s<SUP>-1</SUP>, compared with the 20-100 keV IBIS flux of 3.9 x 10<SUP>-11</SUP> erg cm<SUP>-2</SUP> s<SUP>-1</SUP>, suggests that this may be a Compton thick AGN.X-rayGamma RayAGNStarsSwift/XRT observations confirm the AGN nature of IGR J14175-4641 IGR J14552-5133 and IGR J16351-5806http://adsabs.harvard.edu/abs/2007ATel..990....1L2007ATel..990....1L
