TITLE: GCN CIRCULAR NUMBER: 5921 SUBJECT: GRB 061210: Swift XRT analysis - Possible counterparts DATE: 06/12/14 17:03:18 GMT FROM: Olivier Godet at U.of Leicester O. Godet, K. Page, P. Evans, A. P. Beardmore (U. Leicester), D. N. Burrows (PSU), J. K. Cannizzo (LANL) report on behalf of the Swift XRT team: We analysed 26ks of XRT data for the short burst GRB 061210 (Cannizzo et al., GCN Circ. 5904) taken between 2.42 days and 2.72 days after the BAT trigger. Swift observed this burst late due to a Moon constraint. The XRT/PC image shows two sources S1 and S2 in the BAT error circle located at: S1: RA(J2000)=09h 37m 57.55s Dec(J2000)=+15d 36' 30.8" with an uncertainty of 4.1" (90% containment). The source S1 is 110" from the BAT position quoted in Palmer et al. (GCN Circ. 5905). S2: RA(J2000)=09h 38m 05.17s Dec(J2000)=+15d 37' 16.0" with an uncertainty of 4.2" (90% containment). The source S2 is 30" from the BAT position quoted in Palmer et al. (GCN Circ. 5905). The two sources are uncatalogued. We note that a slightly elliptical object located at 12.1" from the position of the source S2 is seen in the DSS images. This corresponds to the source EO1509-0232011 in the APM-North catalogue. It has a r-magnitude of 17.24 and a b-magnitude of 22.12. With the data so far available we can not tell if either S1 or S2 are fading. However, the XRT will continue to observe the field. This circular is an official product of the Swift XRT Team.
