Sonbas (GSFC/USRA/Adiyaman Univ.)\nreport on behalf of the Swift/UVOT team:\n\nThe Swift/UVOT began settled observations of the field of GRB 110715A\n100 s after the BAT trigger (Sonbas et al., GCN Circ. 12158).\n\nThe preliminary UVOT position is:\n  RA  (J2000) =  15:50:44.09 = 237.68369 (deg.)\n  Dec (J2000) = -46:14:06.53 = -46.23515 (deg.)\nwith an estimated uncertainty of 0.56 arc sec.
