Palmer (LANL) report on behalf of the  \nSwift/UVOT team:\n\nThe Swift/UVOT began observing the field of INTEGRAL GRB 090702,  \n3.5hrs after the\nINTEGRAL trigger (Paizis et al., GCN 9603). We do not detect any  \nsource at the\nSwift XRT position (Sbarufatti et al. GCN 9604).\n\nThe 3-sigma upper limits for the finding chart exposure is:\n\nFilter   T_start(s)   T_stop(s)   Exp(s)  Mag (3-sigma upper limit)\n-------------------------------------------------------------\nwhite      14080       20350        971     > 22.72\nv          14646       20964       1126     > 21.20\nb          13516       25451       1753     > 22.37\nu          12951       24855       1796     > 21.89\n-------------------------------------------------------------\n\nThe quoted upper limits have not been corrected for the expected\nGalactic extinction along the line of sight of E_(B-V) = 0.039 mag.\nAll photometry is on the UVOT photometric system described in Poole et\nal. (2008, MNRAS, 383, 627).",
