Baumgartner (GSFC/UMBC) report\non behalf of the Swift/UVOT team:\n\nThe Swift/UVOT began settled observations of the field of GRB\n100513A 130s after the BAT trigger (Baumgartner et al., GCN 10746).\nWe do not detect any source at the enhanced Swift XRT position\n(Evans et al., GCN 10751) nor at the position of the PAIRITEL NIR\ndetection (Morgan et al., GCN 10747).  UVOT magnitude 3-sigma\nupper limits are reported in the following table:\n\nFilter  T_start  T_stop  Exp(s)  Mag (3-sigma upper limit)\n-------------------------------------------------------------\nwhite     130     1707    411      > 21.29\nv         618     1757    136      > 19.02\nb         544     1683    116      > 19.89\nu         289     1658    343      > 20.22\nuvw1      667     1462     97      > 19.33\nuvm2     5000     5200    196      > 19.59\nuvw2     6026     6226    196      > 20.03\n\nThe quoted upper limits have not been corrected for the expected\nGalactic extinction along the line of sight of E_(B-V) = 0.05 mag\n(Schlegel et al. 1998). All photometry is on the UVOT photometric\nsystem described in Poole et al. (2008, MNRAS, 383, 627).",
