Mao (INAF-OAB) report on behalf of the Swift UVOT team.\n\nThe Swift UltraViolet/Optical Telescope (UVOT) began ToO observations\nof the Swift-BATSS GRB 081025 (Copete et al., GCN Circ. 8409), 20.7 hours\nafter the trigger. We do not detect any new source at the XRT position\nreported in GCN Circ. 8411 (Mao et al.) in any of the individual or\nco-added images down to the following 3-sigma upper limits:\n\nFilter  Tstart(hrs)  Exp(s)  3-sigma UL\nb        21.2        130     > 19.44\nu        20.9        885     > 20.18\nuvw1     20.7        1015    > 20.60\nuvm2     22.2        886     > 20.63\n\nThe values quoted above are on the UVOT Photometric System\n(Poole et al, 2008, MNRAS 383,627).  They are not corrected for the expected\nGalactic extinction corresponding to a reddening of E(B-V)=0.02 mag\nin the direction of the burst (Schlegel et al. 1998).",
