Beardmore (U Leicester) report on\nbehalf of the Swift/UVOT team:\n\nThe Swift/UVOT began settled observations of the field of GRB 110205A\n164 s after the BAT trigger (Beardmore et al., GCN Circ. 11629).\nThe peak near 1000s reported by Klotz et al. (GCN Circ. 11632) and\nAndreev et al. (GCN Circ. 11641) is seen in the UVOT optical filters\nand one of the UV filters (uvw1), consistent with the reported\nredshift z=2.22 (Cenko et al., GCN Circ. 11638 and Vreeswijk et al.,\nGCN Circ. 11640).  The weak detections (2-3 sigma) in uvw2 are\nprobably due to the filter's extended sensitivity in the red.\nAfter 5000s, the estimated temporal slope in the white filter is 1.6.\nPreliminary photometry using the UVOT photometric system (Poole et al.\n2008, MNRAS, 383, 627) for the finding chart (FC) and subsequent\nexposures is:\n\n\nFILTER     TSTART   TSTOP    MAG    +/-   UL(2o)\nwhite_FC     164.0    313.8  18.79  0.07\nwhite        601.9    621.7  17.01  0.08\nwhite        774.6    794.4  15.74  0.06\nwhite_FC     875.4   1025.1  15.36  0.04\nwhite       1181.0   1375.8  15.39  0.05\n\nv            652.0    671.8  15.76  0.11\nv            824.3    844.1  14.98  0.08\nv           1056.5   1251.8  14.68  0.06\n\nb            577.5    597.3  17.10  0.12\nb            750.3    770.1  15.77  0.07\nb           1154.7   1351.5  15.33  0.05\n\nu_FC         321.9    571.7  18.24  0.09\nu            725.4    745.2  15.59  0.09\nu           1130.5   1325.1  15.02  0.06\n\nuvw1         701.0    720.8  18.23  0.41\nuvw1        1106.0   1300.8  17.09  0.17\n\nuvm2         676.3   1276.1               19.89\nuvm2        1430.1   1795.8               19.60\n\nuvw2         627.4   1226.2  19.89  0.49\nuvw2        1381.4   1747.0  19.28  0.41\n\nThe values quoted above are not corrected for the Galactic extinction\ndue to the reddening of E(B-V) = 0.01 in the direction of the burst\n(Schlegel et al. 1998).",
