  "body": "D. E. Vanden Berk (PSU), B. Sbarufatti (INAF-IASFPA), and S. D. Barthelmy\n(GSFC) report on behalf of the Swift team:\n\nUVOT took a finding chart exposure of 100 seconds with the White (160-650\nnm) filter starting 1605 seconds after the BAT trigger.  Because of an\nEarth limb constraint, the spacecraft did not slew promptly to the BAT\nposition.  There is a candidate afterglow in the rapidly available\n2.7'x2.7' sub-image at\n  RA(J2000)  =  05:46:24.46 =  86.6019\n  DEC(J2000) = +64:12:38.5  =  64.2107\nwith a 1-sigma error radius of about 0.5 arc sec. This position is 83.0\narc sec. from the center of the BAT error circle, and 2.5 arc sec. from\nthe center of the XRT error circle. The estimated magnitude is 18.6 with\na 1-sigma error of about 0.5 mag. No correction has been made for the\nexpected extinction corresponding to E(B-V) of 0.18."
