Lien (NASA/GSFC/ORAU) report on behalf\nof the Swift/UVOT team:\n\nThe Swift/UVOT began settled observations of the field of GRB 130122A 121 s\nafter the BAT trigger (Lien et al., GCN Circ. 14140). A source consistent\nwith the XRT position reported in (Beardmore et al., GCN Circ. 14143) is\nseen in the initial exposures.\n\nThe preliminary UVOT position is:\n    RA  (J2000) =  12:57:08.30 = 194.28459 (deg.)\n    Dec (J2000) = +59:00:53.5  =  59.01487 (deg.)\nwith an estimated uncertainty of 0.53 arc sec. (radius, 90% confidence).\n\nPreliminary detections and 3-sigma upper limits using the UVOT photometric\nsystem (Breeveld et al. 2011, AIP Conf.
