We obtained four unfiltered images, with exposure\ntimes of 180 and 480 s.\n   \nThe comparison with the USNO-A2 catalog of the 2.5' error circle around\nthe position provided by INTEGRAL (GCN #2459) as well as the 6\" ones\naround the two positions provided by XMM NEWTON (GCN #2464) does not\nreveal any new source down to a limiting magnitude of V < 17.6. \n\nThis message may be cited.",
