Circ. 9795), gathering 950s of data in the from interval T0+9ks\nto T0+14 ks.\n\nNo optical afterglow consistent with the Swift XRT position (Evans et\nal., GCN 9803)  is detected in the UVOT exposures.  Preliminary 3-sigma\nupper limits, using the UVOT photometric system (Poole et al. 2008,\nMNRAS, 383, 627), are:\n\nFilter   T_start(s)   T_stop(s)   Exp(s)   Mag\nu        8044\t      14166       506      >20.32\nw2       8485\t      8933        441      >20.30\n\nThe values quoted above are not corrected for the Galactic extinction\ndue to the reddening of E(B-V) = 1.10 in the direction of the burst\n(Schlegel et al. 1998).",
