IGR J17419-2802- Discovered by IBIS on 29 September 2005 (Atel #616 Grebnev et al.).- It showed two outburst detected by IBIS : the first on 01 Oct. 2005 and thesecond in 22 Feb. 2006.IBIS mosaic image of the first outburst: 109 ks; 20-40 keV with 13.4 sigma;40-80 keV with 4 sigma
IGR J17419-2802An observation performed by Swift immediately after the discovery in 2005shows a bright counter part with F 2-10keV =3.6x10 -11 erg s -1 cm -2 (Kennea et al2005 ATel #617)Its refined XRT position is given in ATel #745 (Kong 2006):R.A.=17h41m56.0s, Dec=-28d01m54s.5 (J2000) (8” error).This position is consistent with a 2MASS source.Power law spectrum of Γ=1.6+-0.3, N H =1.4x10 22 cm -2 Galactic Centre distance of 8.5 kpc
