Schady (MSSL-UCL) report on behalf of the Swift  \nUVOT team:\n\nThe Swift/UVOT began observing the field of GRB081121 starting 2816  \nseconds\nafter the BAT trigger (Oates et al., GCN 8537) with a White finding  \nchart exposure\nof 150 seconds. There is a candidate afterglow in the 2.7'x2.7' sub- \nimage at\n\nRA(J2000) =\t05:57:06.19 = 89.27581\nDEC(J2000) = -60:36:10.3 = -60.60286\n\nwith a 90%-confidence error radius of about 0.62 arc sec. This  \nposition is 0.7\narc sec. from the center of the XRT error circle and is consistent  \nwith the position\nof the optical afterglow found by ROTSE-IIIc (Yuan el al., GCN 8536).\n\nThe estimated magnitude is 17.98 with a 1-sigma error of about 0.04. No\ncorrection has been made for the expected extinction corresponding to  \nE(B-V) of 0.05.",
