Racusin (NASA/GSFC)\nreport on behalf of the Swift/UVOT team:\n\nThe Swift/UVOT began settled observations of the field of GRB 161014A\n4 ks after the BAT trigger (Racusin et al., GCN Circ. 20035).\nA source consistent with the optical position reported by MITSuME (Morita et al GCN Circ 20036)\nand LCOGT-FTS (Guidorzi et al., GCN Circ. 20037) is detected in the\ninitial UVOT exposures. The lack of detection in the u and UV bands\nis consistent with the redshift of 2.823 reported by GTC\n(de Ugarte Postigo et al., GCN Circ. 20043).\n\nThe preliminary UVOT position is:\n    RA  (J2000) =  22:10:35.46 = 332.64775 (deg.)\n    Dec (J2000) =   7:28:07.3  =   7.46869 (deg.)\nwith an estimated uncertainty of about 0.9 arc sec. (radius, 90% confidence).\n\nPreliminary magnitudes using the UVOT photometric system\n(Breeveld et al. 2011, AIP Conf.
