Mangano (INAF/IASFPA) report on \nbehalf of the Swift XRT team:\n\nFurther observations of the field of GRB 110420B (Sbarufatti  et al.\nGCN Circ. 11944) have shown that the X-ray source reported by Sbarufatti \net al. (GCN Circ. 11947) has not faded.  Moreover, the position is \nmarginally consistent with the known X-ray source 1RXS J212024.5-411816. \nTherefore we conclude that the XRT source is not the burst afterglow.\n\nThis circular is an official product of the Swift-XRT team.",
