  "body": "E. Berger (Carnegie Observatories) reports:\n\n\"Inspection of our Gemini-North/GMOS images taken on 2007 April 8.39 UT in \n0.55\" seeing reveal that the source near the center of XRT source S2 (GCN \n6265), which is classified as a star in SDSS, is embedded within a clearly \nextended source.  This may be a chance superposition of a star on top of a \nbackground galaxy, or more likely, it is a bright AGN, similar to the \nsource coincident with XRT source S1 (GCN 6262).  Additional XRT \nobservations are required to verify whether the source is steady.\n\nWe also note that in addition to the galaxy located 3.7\" from the XRT \nposition, our images reveal five fainter extended sources within the error \ncircle.\"",
