Cummings (GSFC/UMBC), report on \nbehalf of the Swift Team.\n\nSwift-XRT performed further observations on the afterglow candidate \nannounced in Sbarufatti et al. (GCN 12067). The source has faded with \nrespect to the initial observation (1.2E-2 counts/s), and has dropped \nbelow the threshold for detection. The latest observations contain a 20 \nks exposure, corresponding to a 3-sigma upper limit of 1.3E-3 counts/s, \nconfirming that the source was X-ray the afterglow of GRB 110604A.\n\nThis circular is an official product of the Swift-XRT team.",
