B. Sbarufatti (INAF-OAB/IASFPA), J. Cummings (GSFC/UMBC), report on
behalf of the Swift Team.
Swift-XRT performed further observations on the afterglow candidate
announced in Sbarufatti et al. (GCN 12067). The source has faded with
respect to the initial observation (1.2E-2 counts/s), and has dropped
below the threshold for detection. The latest observations contain a 20
ks exposure, corresponding to a 3-sigma upper limit of 1.3E-3 counts/s,
confirming that the source was X-ray the afterglow of GRB 110604A.
