Produit (ISDC), S.Mereghetti, A.Paizis (IASF Milano),\nD.Gotz (CEA-Saclay) on behalf of the IBAS Localization Team report:\n\nthe position of the Swift trigger 421072 (GCN 10708, Pagani et al. 2010)\nwas in the field of view of the INTEGRAL IBIS instrument at the time of\nthe trigger, although at a very large off-axis angle (~9 degrees\noutside the field of view of the JEM-X instrument).\n\nAn analysis of the IBIS/ISGRI image integrated over 90 sec around the\ntime of the trigger, from 4 May 2010 at 7:27:50 UT to 4 May 2010 at 7:29:20\nUT, did not show any source and resulted in an upper limit of 460 mCrab\nin the 20-40 keV energy range (3 sigma c.l.).\n\nAlso integrating over a longer time interval (~2000 s), from 4 May 2010\nat 7:00:23 UT to 4 May 2010 at 7:32:53 UT, no source is detected\nwithin the Swift error region, and the corresponding upper limit\nis 65 mCrab (20-40 keV).\n\nThis message can be cited.",
