SUBJECT: GRB 110420B: Swift-XRT afterglow candidate retraction

B. Sbarufatti (INAF-OAB/IASFPA) and V. Mangano (INAF/IASFPA) report on
behalf of the Swift XRT team:
Further observations of the field of GRB 110420B (Sbarufatti et al.
GCN Circ. 11944) have shown that the X-ray source reported by Sbarufatti
et al. (GCN Circ. 11947) has not faded. Moreover, the position is
marginally consistent with the known X-ray source 1RXS J212024.5-411816.
Therefore we conclude that the XRT source is not the burst afterglow.
This circular is an official product of the Swift-XRT team.
