TITLE: GCN CIRCULAR NUMBER: 5924 SUBJECT: GRB061210: Swift/UVOT observations DATE: 06/12/15 00:39:38 GMT FROM: Antonino Cucchiara at PSU Cucchiara A. (PSU), Cannizzo J. (NASA/UMBC) reports on behalf of the Swift/UVOT team: The Swift/UVOT observed the field of GRB061210 starting 2.42 days after the BAT trigger (Cannizzo et al., GCN Circ. 5904). No afterglow optical candidate is detected in either of the XRT error circles in 18.5 ks of exposure time from T+2.42 days to T+3.48 days in U band. We clearly detect the extended source near the candidate S1 (Berger et al., GCN Circ. 5922) at the following coordinates: RA(J2000) = 09:37:57.92 DEC(J2000) = +15:36:32.6 with a 1 sigma error radius of about 0.5 arcsec. The estimated UVOT/U magnitude is 21.0 +/- 0.1. In a second epoch image taken from T+3.5 days to T+3.64 after the trigger the source is still present and it is not fading. The estimated magnitude in 12 ks coadded image is 21.0 +/- 0.1. In the position of the candidate S2 we estimate a 3 sigma upper limit of 22.06. The values quoted above are not corrected for the expected Galactic extinction of E_{B-V} = 0.035 mag (Schlegel et al. 1998).
