Marshall (NASA/GSFC)\nreport on behalf of the Swift/UVOT team:\n\nThe Swift/UVOT began settled observations of the field of GRB 140706A\n82 s after the BAT trigger (Marshall et al., GCN Circ. 16531).\nA fading source consistent with the XRT position\n(Beardmore et al. GCN Circ. 16532)\nis detected in the initial UVOT exposures.\n\nThe preliminary UVOT position is:\n  RA  (J2000) =  03:17:10.39 =  49.29328 (deg.)\n  Dec (J2000) = -38:03:07.8  = -38.05218 (deg.)\nwith an estimated uncertainty of 0.45 arc sec.
