  "body": "M. Perri, L. Vetere (ASDC), D.N. Burrows (PSU) report on behalf of\nthe Swift XRT team:\n\nThe Swift XRT observed the field of GRB 060322 (GCN 4903, Perri et al.)\nfor a second time on 2005-03-25 from 00:37:09 UT until 21:53:57 UT.\nWe confirm that the X-ray source identified by Perri et al. (GCN 4919,\nRA(J2000) = 18h 16m 56.4s, Dec(J2000) = -36d 42' 31\" )\nhas faded from view and is therefore the likely X-ray afterglow of\nthis burst.\n\nUsing an exposure of ~11 ks in Photon Counting mode we place a three\nsigma upper limit on the 0.3-10 keV count rate of 2.0e-3 cts/s which\nis significantly lower than the count rate observed with the first\nexposure (3.0+/-0.7)e-3 cts/s, implying that the source has faded.\n\nWe conclude that the candidate reported in GCN 4919 is the X-ray\nafterglow of GRB 060322.\n\nThis circular is an official product of the Swift XRT Team.",
