Sonbas (Adiyaman Univ.)\nreport on behalf of the Swift/UVOT team:\n\nWe report further on the Swift/UVOT observations of GRB 160325A which\nbegan 75 s after the BAT trigger (Sonbas et al., GCN Circ. 19222). A\nsource was reported earlier by McCauley et al. (GCN Circ. 19228), which\nwas consistent with the XRT position (Evans et al., GCN Circ. 19229)\nand infrared detection (Fugazza et al., GCN Circ. 19223).  We confirm\nthat the source is rapidly fading.\n\nPreliminary detections and 3-sigma upper limits using the UVOT\nphotometric system\n(Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the early exposures are:\n\nFilter         T_start(s)   T_stop(s)      Exp(s)           Mag\n\nwhite               75          224          146         15.65+-0.05\nwhite              567         1187          205         17.24+-0.05\nwhite             7227        12203          231         19.59+-0.16\nv                  617          809           38         15.12+-0.07\nv                 1044         1237           38         15.79+-0.10\nv                 1392         6402          216         17.73+-0.14\nb                  543          735           38         17.11+-0.11\nb                 1143         1510           58         18.70+-0.33\nb                 7023         7222          196        >19.64\nu                  287          537          245         18.91+-0.22\nu                  691         7017          274        >19.47\nuvw1               666         1461           97         18.36+-0.32\nuvw1              6613         6812          196         19.05+-0.33\nuvm2               641         1263           77         18.30+-0.34\nuvm2              1416         6607          216         18.73+-0.29\nuvw2               593         1387           97        >18.63\nuvw2              5998         6197          196         18.30+-0.19\n\nThe magnitudes in the table are not corrected for the Galactic extinction\ndue to the reddening of E(B-V) = 0.04 in the direction of the burst\n(Schlegel et al. 1998).",
