GCN Circular 9987
C. Gronwall (PSU) and R.L.C. Starling (U. Leicester) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 091003 approximately 15.5 hours after the Fermi/GBM trigger (Rau, GCN Circ. 9983). In a 885 sec observation in the uvw2 filter, we find a faint candidate fading UV afterglow within the XRT error circle (Starling & Beardmore, GCN Circ. 9986). The estimated magnitude is 21.02 +/- 0.27. This value is not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.02 in the direction of the burst (Schlegel et al. 1998).
