TITLE: GCN CIRCULAR NUMBER: 12933 SUBJECT: GRB 120212A: Swift/UVOT detection DATE: 12/02/12 10:59:39 GMT FROM: Erik Hoversten at Swift/Penn State E. A. Hoversten (PSU) and E. Sonbas (NASA/GSFC/Adiyaman Univ.) report on behalf of the Swift team: UVOT took a finding chart exposure of 150 seconds with the White filter starting 2885 seconds after the BAT trigger. The source identified by Guidorzi et al. (GCN Circ. 12932) is detected in the rapidly available 2.7'x2.7' sub-image at RA(J2000) = 02:52:24.06 = 43.10025 DEC(J2000) = -18:01:14.1 = -18.02057 with a 90%-confidence error radius of about 0.76 arc sec. This position is 5.21 arc sec. from the center of the XRT error circle. The estimated magnitude is 18.31 with a 1-sigma error of about 0.15. No correction has been made for the expected extinction corresponding to E(B-V) of 0.03.
