With reference to the RXTE discovery of XTE J1824-141, a new intermittent 120 sec pulsar (Atel 1679), we note that the unidentified INTEGRAL source IGR J18246-1425 belonging to the 3rd IBIS Survey Catalogue (Bird et al. 2007, ApJS, 170, 175) is at a distance of 18 arcmin well within the 30 arcmin PCA error box. The IBIS source position is (RA,Dec) =276.161, -14.418 (J2000) with an uncertainty of 4.4 arcminutes. The 20-40 keV source flux is 1.1+/-0.1 mCrab while at 40-100 keV it is 0.6+/-0.2 mCrab. We encourage follow-up observations of this possible counterpart.
