Holland (CRESST/USRA/GSFC) reports on behalf of the Swift/UVOT\nteam:\n\n     The Swift/UVOT observed the field of GRB 080514B starting 37,005 s\nafter the SuperAGILE/IPN detection (Rapisarda et al., GCN Circ. 7715).\nWe detect the optical afterglow in the b, u, uvw1, and uvm2 filters at\nthe location of the IAC80 optical afterglow (de Ugarte Postigo, et al.,\n2008, GCNC 7719).  The UVOT source position is\n\n  RA(J2000.0) =  21:31:22.71\nDec(J2000.0) = +00:42:28.4\n\nwith an estimated uncertainty of +/-0.60 arcsec (radius, 90%\nconfidence).\n\n     Magnitudes and upper limits are reported below.\n\nFilter    T_start (s) T_stop  Exposure   Mag    Err  Comment\n   v       38,184     43,906      352    >20.1        3-sigma UL\n   b       37,449     48,630      559     20.92 0.27\n   u       37,229     48,415      559     19.97 0.17\n  uvw1     37,005     48,198     1118     20.74 0.24\n  uvm2     38,333     44,537     1030     20.83 0.32\n  uvw2     37,601     49,441     2199    >22.1        3-sigma UL\nwhite    209,879    228,394     5360    >23.3        3-sigma UL\n\nThe above magnitudes and upper limits are not corrected for the\nGalactic extinction along the line of sight corresponding to a\nreddening of E_{B-V} = 0 .06 mag (Schlegel et al., 1998, ApJS,\n500, 525).
