Abstract
IGR J12131+0700 (not NGC 4180) The third IBIS survey contains a source at RA(J2000) = 183.291 and Dec(J2000) = +7.009, initially associated to the galaxy NGC 4180, which has been recently classified as a possible Seyfert 2 galaxy (Masetti et al. 2007, Atel 1033). Swift/XRT has now observed this sky region for 4.6 ksec and detected within the IBIS uncertainty (5.1 arcmin), two sources at 1) RA(J2000) = 12h 12m 49.62s, Dec(J2000) = +06d 59s 44.6s (5.1 arcsec uncertainty, 5.3 sigma) 2) RA(J2000) = 12h 12m 56.60s, Dec(J2000) = +07d 03s 06.7s (6 arcsec uncertainty, 3.6 sigma) Object N.1 coincides with the QSO SDSS J121249.84+065945.4 (also NVSS J121249+065950) at z = 0.2095 and has a 2-10 keV flux of 1.5 x 10<SUP>-13</SUP> erg cm<SUP>-2</SUP> s<SUP>-1</SUP> (Gamma = 1.8).
