  "body": "C. Blake (Harvard) and J. S. Bloom (UCB) report:\n\nPAIRITEL has continued to image the Yost et al. optical candidate\nafterglow (GCN #3322). We confirm that the IR source (#3326) initially\nfaded, strongly confirming the hypothesis from Yost et al. In\nparticular, from T+47min to T+94 min the source faded by ~1.1 mag in\nJ. But from T+94 min to T+121 min, there is some evidence for\nbrightening by ~0.1 mag in J-band. A similar result is found in H and\nKs.\n\nBased on an astrometric tie of 2MASS to a 141 sec J-band image from\n(start) 2005-05-02 02:52:40 UT, we find\n\n  IRT:  RA = 13:29:46.33, Dec = 42:40:27.3    --Offset to IRT--\n  A :   RA = 13:29:42.78, Dec = 42:40:49.2  21.83\"   S, 39.19\" E\n  B:    RA = 13:29:44.23, Dec = 42:38:13.1  134.20\"  N, 23.21\" E\n\nThe uncertainty in the absolute WCS is ~0.5 arcsec.  Sources A and B are\nnearby bright sources suitable for blind offset spectroscopy.\"",
