TITLE: GCN CIRCULAR NUMBER: 7369 SUBJECT: GRB 080307: Gemini-N i-band observations - candidate afterglow DATE: 08/03/07 15:05:05 GMT FROM: Nial Tanvir at IofA U.Cambridge N. R. Tanvir (U. Leicester) reports on behalf of a larger collaboration. We observed the field of GRB 080307 with Gemini-N/GMOS, beginning at 12:50 (UT), approximately 85 minutes post-burst. We detect a point source in the i-band image within the XRT error circle (GCN 7366) with (J2000) coordinates: 09 06 30.78 +35 08 20.0 Provisional photometry relative to field SDSS stars gives a magnitude of i=22.4 at this time. We thank the Gemini staff, particularly Ricardo Schiavon, for support in obtaining these observations.
