Cummings (GSFC/UMBC), \non behalf of the Swift/UVOT team.\n\nThe Swift Ultra-Violet/Optical Telescope (UVOT) began settled observations \nof the Swift-BAT and IPN localization GRB 081105 (#333811; Cummings et \nal., GCN 8484) ~16 hours after the BAT trigger. No afterglow is detected \nat the XRT position (Beardmore et al., GCN 8487) in any filter. The \n3-sigma limiting magnitudes in each of the observed UVOT filters are as \nfollows:\n\nFilter  T_start(dys) Exp(s)  Mag UL (3sig)\n\nwhite     0.67        159     > 20.76\nv         0.81        630     > 19.92\nb         0.66        885     > 21.05\nu         0.74        224     > 19.92\nuvw1      0.73        886     > 20.75\nuvw2      0.89        886     > 21.02\n\nThe values quoted above are in the UVOT photometric system (Poole et al. \n2008, MNRAS, 383, 627).  They are not corrected for the expected Galactic \nextinction corresponding to a reddening of E(B-V)=0.03 mag in the \ndirection of the burst (Schlegel et al. 1998).",
