De Pasquale (MSSL-UCL), and D.C.\nMorris (GWU/GSFC) report, on behalf of the Swift team:\n\nSwift XRT and UVOT instruments began observing the field of INTEGRAL\nburst GRB 110112B (Mereghetti et al., GCN circ 11562) 55.8 ks after the\nburst trigger. No candidate afterglow is detected in the INTEGRAL error\ncircle.\n\nUVOT and XRT observed the field of view from 55.8 ks until 67.3 ks after\nthe trigger. UVOT observed in white filter, with a total exposure time\nof 3.6 ks. The three sigma upper limit for any new source in the field\nof view is 22.2 mag. XRT observations have a total exposure time of 4.9\nks, and yield a three sigma upper limit of 2.0e-3 counts/second for any\nnew source in the field of view.\n\nThis circular is an official product of the Swift Team.",
